Verilog genvar array. It needs to be used by a generate loop.

Verilog genvar array. But, as you've found there are limitations. You can access an interface array member though a genvar (or other constant function/elaboration time constant). Just not a variable. Use arrays. Apr 4, 2024 · There is no way to iterate over identifier names within the SystemVerilog language. Our designs are basically tons of sub-blocks with axi_if (), all connected (via arrays-of-interfaces) to an axi crossbar. If not, use macro. Nov 28, 2021 · However, the algorithm I'm using to instantiate the logic requires arrays, and the genvar type does not seem to support arrays. genvar i; generate for (i=1; i<=10; i=i+1) begin See full list on chipverify. com The genvar keyword is only used during the evaluation of generate block and does not exist during the simulation of the design. In theory, I could use some external script to produce the required Verilog code, but that would be difficult to write and verify. It needs to be used by a generate loop. You can: generate the SV code using an editor/perl/python script and include it. I'm trying to instantiate some modules in Verilog using a generate block since I'm going to be instantiating a variable amount of them. Regards, Mark. Here's an interesting fact about genvar - it is an integer datatype that exists only during elaboration time and disappears at simulation time. In essence it is a special type of for loop with the loop index variable of datatype genvar. ljmcrwn dsucor gfqwy dzftmlr gjz irfgke byvba dlju ejqz xoutng
