Xilinx Spartan and Spartan-XL FPGA Families

Are the Xilinx Spartan and Spartan-XL FPGA Families Really Useful?

The Xilinx Spartan and the Spartan-XL FPGA families offer a FPGA solution with high-volume production, which provides all the major requirements for all ASIC replacements with 40,000 gates possible. The FPGA here means Field Programmable Gate Arrays. The requirements here include on-chip RAM, high performance, core prices and solutions, XCS05 approach, and in majority of cases, you can liken them to ASIC devices that have undergone mask programming.

With the streamlining of the feature set of the Spartan series, as well as leveraging process technologies and then focusing on the management of total cost, this Spartan series offers the main features necessary for ASIC as well as other logic users of high-volume while avoiding long cycles of development, initial cost, as well as conventional ASICs’ inherent risk.

Spartan series Field Programmable Gate Arrays (FPGAs) are implemented using a programmable, flexible, regular, architecture of CLBs (Configurable Logic Blocks), with interconnection done by a strong hierarchy of routing channels (routing resources), and with programmable IOBs (input and output blocks surrounding it. Furthermore, they possess routing resources which help in accommodating interconnect patterns that are most complex.

You can customize the devices by loading the configuration data to the internal memory cells. Also, you can re-program so many times; there’s no limit to this. Whatever values are present in the memory cells helps in determining the interconnections and logic functions the FPGA implements. Furthermore, the FPGA can either read the configuration data actively from an serial PROM (external), or from the external device, you can write the configuration data in the Field Programmable Gate Arrays (FPGA).

General Overview of the Xilinx Spartan and Spartan-XL FPGA Families

The Xilinx Spartan and Spartan-XL FPGA Families are useful where it is necessary to adapt the hardware to several user applications. Also, FPGAs are great for the development and shortening design cycles. Furthermore, they provide a low-cost solution for rates of production far above 50,000 systems each month.

In addition, the Xilinx Spartan and Spartan-XL FPGA Families devices offer low-cost, high-performance operation via using advanced semiconductor and architecture technology. Also, the Xilinx Spartan and Spartan-XL FPGA Families devices offer rates for system clocks surpassing 80 MHz, as well as an internal performance as high as 150 MHz.

In comparison with other similar FPGA devices, this Spartan series provides the best cost-effective solution coupled with the maintenance of leading-edge performance. Asides from the benefit of programmable, high-volume logic solutions, these FPGAs also provide edge-triggered on-chip dual-port and single-port RAM, the clock functions on all fast carry logic, flip-flops, as well as many additional features.

Furthermore, the Xilinx Spartan and Spartan-XL FPGA Families leverage the XC4000 architecture, which is known to be a very successful XC4000 with a good number of benefits and features of that family. The derivation of advancements in technology is from the process developments of the XC4000XLA.

Logic Functional Description of the Xilinx Spartan and Spartan-XL FPGA Families

The Xilinx Spartan and Spartan-XL FPGA Families utilize a standard structure for the FPGA. This FPGA is made up of an arrangement of CLBs (configurable logic blocks), which are placed into a routing channels’ matrix. In addition, the signals’ output and input is achievable via some IOBs (input and output blocks). This is possible by the formation of a ring round the routing channels and CLBs.

  • CLBs offer those functional elements necessary for the implementation of the logic of the user.
  • Also, IOBs offer the interface in-between the signal lines (internal) and the package pins.
  • In addition, the routing channels offer paths that aid the interconnection of the outputs and inputs of the IOBs and CLBs.

The customization of each circuit board’s functionality is possible when configuration occurs by the programming of the internal memory cells (static). Also, the storing of the values in the memory cells helps in determining the interconnections and logic functions that the FPGA implements.

Configurable Logic Blocks (CLBs)

CLBs are useful for the implementation of the majority of an FPGA’s logic. Three LUTs (look-up tables) are present and serve as generators for logic functions, two signal steering multiplexers groups, as well as two flip-flops. Furthermore, there are some advanced features the CLB offers. Let’s consider them

Function Generators

Two 16 x 1 tables (G-LUT and F-LUT) are useful for the implementation of generators of 4 input functions, with each delivering a logic implementation of all Boolean functions of about four input signals (G1 to G4 or F1 to F4). Furthermore, when making use of look-up tables, the delay in propagation works independently of the implementation of the function.

A 3rd generator for 3-input function (H-LUT), functions in implementing Boolean functions of three inputs. Programmable multiplexers control 2 of the inputs. Also, these inputs may show up from either the G-LUT or F-LUT outputs. It can also come from the CLB inputs. All the time, the 3rd input comes from an input of the CLB.

Therefore, the CLB has the ability to incorporate some functions of about nine inputs, such as parity checking. Also, you can combine the CLB’s three LUTs to do all five inputs Boolean function that are arbitrarily defined.

Functions of a Configurable Logic Block

With a CLB, you can achieve any of these functions:

  • All functions that have about four variables, in addition to a second function that has about four variables that are unrelated, in addition to any other third function that has about three variables that are not related. Note that when you generate three different functions, you must capture one of the outputs of the function into a flip-flop and also internal to the configurable logic block (CLB). Just two generator outputs with unregistered function can be seen from the configurable logic block.
  • Any of the five variables’ single function
  • Also, any combination of four variables’ function with some of the functions present in six variables
  • Lastly, are some functions that can reach nine variables

The implementation of wide functions in one block helps in reducing both the necessary amount of blocks and the signal path delay. This makes both increase in speed and capacity possible.

The configurable logic block function generators are versatile. This is why they can improve the speed of the system significantly. Furthermore, these tools for the design software deal with every function of the generator independently. Its flexibility helps in improving cell usage.

Flip-Flops

Each configurable logic block features two flip-flops, which are useful in registering the function of the generator outputs.

Furthermore, you can also use the function generators and flip-flops independently. The Configurable logic block input DIN is useful as an input to any of the two flip-flops. Furthermore, the H1 can drive any of the flip-flops through the H-LUT. However, this comes with a little delay.

Also, both flip-flops feature set/reset (SR), clock enable (EC), and common clock (CK) inputs. Internally, you can control the two flip-flops using a GSR (global initialization signal.

Latches (Only for Spartan-XL)

You can also configure the storage elements of the Spartan-XL configurable logic block (CLB) as latches. Both latches feature clock enable (EC) and common clock (K) inputs.

Clock Input

Importantly, you can trigger each of the flip-flops on either the rising or the falling edges of the clock. Furthermore, the two flip-flops share the clock line of the configurable logic block.

Moreover, for each of the flip-flops, you can invert the clock individually. All the inverter placed on the design’s clock line is absorbed in the configurable logic block automatically.

Clock Enable

Here, the line of the clock enable (EC) is high. In a configurable logic block, the two flip-flops share the line of the clock enable. If you disconnect any of them, that flip-flop’s clock enable will default to its active state. Importantly, you cannot invert clock enable within the configurable logic block (CLB). Also, the clock enable is coincident to the clock. Furthermore, it has to satisfy the device’s hold timing and setup.

Set/Reset (SR)

Another is the set/reset line. This is the flip-flop’s active asynchronous high control. You can configure set/reset as either reset or set at each of the flip-flops. With this option for configuration, it helps in determining the state at which each of the flip-flops starts becoming operational immediately after configuration.

Furthermore, it determines the GSR pulse’s effect when normal operation is on, as well as a pulse’s effect on the configurable logic block’s SR line. Also, both flip-flops share this SR line.

If a flip-flop doesn’t specify an SR, then that flip-flop’s set/reset defaults into an inactive state. Importantly, note that you cannot invert SR within the configurable logic block.

Signal Flow Control of the CLB

Asides from the control multiplexers of the H-LUT input, also present are control multiplexers of the signal flow. The latter chooses the signals that drive the inputs of the flip-flop and the combinatorial outputs of the CLB (X and Y).

Furthermore, the flip-flop inputs are driven from a multiplexer (4:1) that chooses from the three outputs of the LUT and DIN as the source of data. You drive every combinatorial output from a multiplexer (2:1). This chooses between two of the outputs of the LUT. You can drive the X output from the H-LUT or F-LUT, and then the Y output also from the H-LUT or G-LUT.

Control Signals

On the configurable logic board, there are 4 multiplexers for signal control. With these multiplexers, you can drive the control signals of the internal CLB from one of the 4 control inputs (general) into the Configurable logic board. Note that you can drive any of the control signals using these inputs.

The four signals for internal control are: Enable Clock (EC), H function generator input, Direct In (DIN), and Set/Reset (SR).
