Input/Output Block

Every IOB offers an interface between the internal user logic and external package pin of the device. Also, every IOB comprises direct input paths and registered paths. Every IOB offers a 3-state output buffer which a direct output signal may drive. With the configuration options, every IOB can have an inversion and a high impedance pull up.

Furthermore, each input circuit features input clamping diodes. This offers electrostatic shielding and helps circuits to posses latch-up generated by input currents. Also, each I/O block comprises output and input storage elements and options chosen by configuration memory cells. Each IOB has an input-buffer option that offers the detection of threshold to translate external signals to internal logic levels.

You can program the global input-buffer threshold to be compatible with CMOS or TTL levels. Also, the buffered input signal may be configured as a latch or flip-flop. The transition times of inputs should be less than 100 ns to achieve reliable operation. Also, the input should not float. Floating input-pin circuits can generate oscillations. Furthermore, there can be more system noise and additional power dissipation.

Each user input/output block comprises a pull-up resistor selected by the program to offer a constant High. The field programmable gate array offers circuitry to prevent any form of electrostatic discharge. Therefore, it is crucial to observe CMOS handling precautions.

In addition, flip-flop delays for input/output block are usually short and as such offering great performance in data and asynchronous clock conditions. IOB buffers must be compatible with CMOS. Also, the network driving Input/output pin becomes the direct data source.

Configurable Logic Block

Configuration logic blocks offer functional elements. These logic blocks are usually arranged within the perimeter of input/output blocks. For instance, the XC3020A comprises 64 blocks in 8 columns and 8 rows. Also, the development system compiles the configuration memory to specify the interconnection and operation of every block. Automatic translation can perform user definition of CLBs.

Every configurable logic block features a combinatorial logic section, internal control section, and two flip flops. Furthermore, there are five different logic units, an enable clock, and an asynchronous direct RESET input, a common clock input.  The interconnect elements adjacent to the blocks may drive all units and clocks. Also, every CLB features two outputs which are X and Y. This may trigger interconnect networks.

The combinatorial logic features F or G outputs which supply data input for any flip-flop within a CLB. The two flip-flops in every CLB have similar asynchronous RD.

Flexible routing enables individual or common CLB clocking. The CLB has a combinatorial logic portion which integrates a 32 by 1 look-up table (LUT) to incorporate Boolean functions. Also, variables chosen from two internal block and five logic inputs serve as table address inputs.

Types of Resources for Different Network Interconnect Requirements

Programmable interconnection resources in Xilinx FPGA board offer routing paths to link outputs and inputs of CLB and I/O blocks into logic networks. Also, interconnections that occur between blocks usually comprise a grid of metal segments. The development system offers routing of these interconnections. Basically, there are three different kinds of metal resources that accommodate different network interconnect requirements. These include:

  • Direct connection
  • General purpose interconnect
  • Longlines

General purpose interconnect

General purpose interconnect features a grid of five vertical metal sections and five horizontal metal sections between columns and rows of IOBs and logic. Furthermore, every section is the width or height of a logic block. You can use switching matrices to join the ends of these sections and enable programmed interconnection between the metal sections of rows and columns. Analog devices

Automatic routing may help establish the connections via the switch matrix. Alternatively, you can choose pairs of matrix pins you need to disconnect or connect. Also, the general interconnect areas have special buffers which offer signal isolation for enhanced performance of lengthy nets. Furthermore, the interconnect buffers enable signal propagation in any direction on a particular general interconnect section.

Direct interconnect

This interconnect offers great networks implementation between adjacent IOBs or CLBs. Signal could posses low interconnect propagation when you use the direct interconnect to route signals from one block to another. For every CLB on an FPGA board, it is important to connect the X output directly to the CLB’s B input to its right and then the C input to its left.

Furthermore, the D input block can be driven by direct interconnect above. Direct interconnect can help to improve the speed of high-performance parts of logic. Direct connect is alternate to the I/O block inputs wherever logic blocks become adjacent to IOBs.


The longlines are mainly intended for signals that need to travel a long distance. There are three vertical longlines on each interconnection column and there are two horizontal longlines on each interconnection row. An Input/output block or a logic block can drive longlines. This helps to offer a clock line or low skew control within every column of logic blocks. You can program longlines as connectable half-length lines.
