The Basic Programmable Functional Elements of Spartan-3A DSP FPGA Family

The Xilinx Spartan-3A DSP architecture features five basic programmable functional elements.

Input/Output Blocks

These blocks regulate data inflow and outflow between the internal logic and I/O pins. I/O blocks allow the bidirectional flow of data and 3-state operation. Also, these blocks support several signal standards. These include many differential standards like the Double Data-Rate registers.

Block RAM

This offers data storage in 18-Kbit dual-port blocks.

XtremeDSP DSP48A Slice

This offers an 18-bit x 18-bit multiplier. Also, it features cascade capabilities for different DSP applications. In addition, it has a 48-bit post-accumulator and 18-bit pre-adder.

Digital Clock Manager Blocks

These blocks offer digital solutions for diving, multiplying, and phase-shifting clock signals. The DCM blocks are in the center with two at the bottom and two at the top of the device.

Configurable Logic Blocks

These blocks comprise Look-Up Tables (LUTS) that use logic plus storage elements. The configurable logic blocks carry out various logical functions. Also, they help to store data. The CLB features outputs, inputs, and digital logic.

The Configuration of Spartan-3A DSP FPGA Family

Xilinx Spartan-3A DSP loads configuration data into reprogrammable CMOS configuration latches (CCLs). These latches are responsible for controlling all routing resources and functional elements. Also, the configuration data of the FPGA is externally stored in a PROM. In addition, there are seven different modes in FPGA. These modes help you to write the configuration data. They include:

  • Boundary Scan (JTAG)
  • Serial Peripheral Interface
  • Master Serial
  • Slave Parallel
  • Byte Peripheral Interface
  • Slave Serial

In addition, Spartan-3A DSP enables you to store two or more configuration bitstreams in a BPI or SPI. The FPGA application decides which configuration to load and the time to load it. Also, each Spartan-3A DSP comprises a Device DNA identifier. Furthermore, this Device DNA is factory-programmed and is ideal for tracking purposes.

I/O Capabilities of Spartan-3A DSP FPGA

The Select I/O interface of Spartan-3A DSP supports several differential and single-ended standards. Spartan-3A DSP supports these single-ended standards:

  • 3V PCI at 66 or 33 MHz
  • 3V low-voltage TTL
  • SSTL I and II at 2.5V, 1.8V, and 3.3V
  • Low voltage CMOS

Also, Spartan-3A DSP supports these differential standards:

  • Bus LVDS I/O at 2.5V
  • Differential SSTL and HSTL I/O
  • TMDS I/O at 3.3V

Guidelines for Simultaneously Switching Output

There are guidelines for the number of Simultaneous Switching Outputs (SSOs). These guidelines define the highest number of user I/O pins of a particular output signal standard. Also, this standard must switch simultaneously in the same direction. In addition, these guidelines must be well-met for the stated test conditions. Also, these guidelines ensure that the FPGA functions free of adverse effects of power bounce.

Power or ground bounce can happen when some outputs switch simultaneously in a similar direction. The output drive transistors conduct current to a voltage rail. Also, high-to-low transitions all conduct to the GND rail. Also, low-to-high transitions all conduct to the Vcco rail. The cumulative current transient causes a difference in voltage across the inductance. This inductance is the one existing between the power supply and the die pad.

Furthermore, the inductance is commonly associated with the package lead frame and bonding wires. Other variables influence the noise levels in SSO. This includes stray inductance and also capacitive loading at receivers. The internal switching noise margins depend on an SSO-induced voltage.

Furthermore, the maximum SSO values believe that the FPGA is fully soldered on the PCB. Also, the PCB uses sound design practices. The SSO values aren’t applicable for FPGAs installed in sockets. This is because of the lead inductance the socket introduced.

Types of Pin in Xilinx Spartan-3A DSP FPGA Family

Here, we are discussing the different types of pins on the Spartan-3A DSP. These pins connect within the packages and components. Also, they offer thermal characteristics for each device. The majority of pins on this FPGA are user-defined I/O pins. However, the Spartan-3A DSP has about 12 functional pins. These pins are:

DUAL

You can use this pin in some configuration modes. Also, you can use DUAL pins during the process of configuration. This pin will act as an I/O-type pin if not used during configuration.

CONFIG

There are two configuration pins per device. Each package comes with two dedicated configuration pins. These pins are fully powered by Vccaux.

I/O

This is a multi-purpose user-I/O. You can pair most pins to create differential I/Os.

VERF

This is a dual-purpose pin that is an input-only pin or a user-I/O pin. This pin offers a reference voltage input for specific I/O standards. Also, all VERF pins within the bank must connect.

INPUT

This pin doesn’t feature an output structure or PCI clamp diode.

JTAG

There are four dedicated JTAG pins for each device. Each package comprises four dedicated JTAG pins. VCCAUX powers each of these pins.

VCCO

This pin can transmit power to the output buffers. However, it does this with other VCCO pins in a similar bank. Ensure you connect all VCCO pins.

GND

This is the dedicated ground pin. The type of package utilized influences the number of GND pins. However, you must connect all ground pins.

PWR MGMT

These pins are the status and control pins for Suspend mode. Also, VCCAUX powers the SUSPEND mode. AWAKE pin is dual purpose.
