Is it illegal to use an (enum) as a Verilog function input?

September 17, 2020, 1:24 am

I'm still very much interested in finding out whether or not it's possible for a Verilog function to have a boolean value as input, but while I was wa iting for input on that I decided to rewrite ... Read more »

Can anyone explain "cannot currently create a parameter of type" ...

September 17, 2020, 1:22 am

I've written a piece of code with inputs (left) and (right) and output (result), each of which operand is a single bit, which returns a logical one in (result) if (left) has the same value as (right)... Read more »

Can a Verilog function take a boolean argument?

September 17, 2020, 1:18 am

I've got a Verilog function that I'd like to behave slightly differently depending on the value of a boolean argument, an argument whose value can be either (true) or (false). I tried: [code] modul... Read more »
