Specific FPGA-based functions, as well as the interconnects between those functions, are “described” in an HDL. The description is compiled to produce an FPGA configuration file. Using a hardware description language, it is possible to use built-in FPGA resources (memory arrays, PCI cores and...

The specific arrangement and interconnection of these transistors define the functionality of the ASIC. This is where the "application-specific" part of ASIC comes into play. The transistors are arranged so that they perform a specific function or set of functions, such as digita...

Hi All, I have a Verilog testbench where I would like to force some signals. I'm using the following code in my Verilog file: $nc_force("/full_path/sugnal_name"
With the dramatic expansion of semiconductor technology, there is a movement toward a need for a larger platform of tools and technologies which may signal the next phase of the industry’s development.Why is EDA Important? Semiconductor chips are incredibly complex. State-of-the-art devices can...
Here’s a simple example of an AND gate in both languages. An AND gate has two inputs and one output. If the inputs are both equal to 1, the output is 1. If they are not equal or if both are set to 0, the output is 0. VHDL describes an AND gate as: entity my_and is...
In ISE Design Suite 11.2, XST introduced a new VHDL/Verilog parser for Virtex-6 and Spartan-6 families. The new parser brings a lot of improvements to the XILINX Synthesis solution. - Significantly enlarges VHDL/Verilog language coverage, including a great support for complex data structures suc...
