I want to make ELU function in the verilog-A code, but it shows syntax error continuously. But the Verilog-A document says that this is the correct syntax, so I would like to ask you what should I fix. module myVerilogAmodel(d, g, s); //* in...
It is also possible for us to use an else-if type statement here but the else statement is more succinct. The behaviour is the same in both cases as the signal can only ever be 0b or 1b in a real circuit. Verilog Case Statement We use the verilog case statement to select a block ...
In Verilog, blocking assignments (=) and non-blocking assignments (<=) are fundamental for describing how signals are updated in simulation cycles. Blocking assignments execute sequentially, one at a time, and the next statement waits for the current one to complete before proceeding. On the othe...
When a variable is larger than required to hold a value being assigned, Verilog pads the contents on the left with zeros after the assignment. This is consistent with the padding that occurs during assignment of non-string values. Certain characters can be used in strings only when preceded by...
I got a problem with a normally relatively straightforward piece of Verilog code representing some modulo arithmetics and an if-statement. In the code below, the modulo of the registers a and b is calculated ( c=a mod b). The next if statement then checks if c, the result of...
We use arrays of interfaces quite extensively, and find them extremely useful in moving our coding up a level of abstraction. I think interfaces (and arrays of them) are one of the best features of SystemVerilog for design. Our designs are basically tons of sub-blo...
