A parameter with an undesired value can lead to both very obvious errors (mismatch in size of a wire to a port) or to very subtle errors (e.g. a parameter used to count a number of clock cycles before reporting an error is set too large to ever get triggered). For this reason, it...
if the modulemainhas the parameterWIDTH, set the width like this "+parameter+main.WIDTH=5". Note the use of the complete hierarchical name. This currently only works for parameters defined in root (top level) modules and a defparam may override the command file value. ...
parameter This makes design more generic module definition module signals and variables wire, reg, tri Vectors are allowed instantiation module instances / primitive gate instances E.g.- nand (out,a,b), bad idea to code RTL this way. function and tasks function , task Timing ...

The clock port(s) must be declared first in the port list, followed by any and all reset inputs. Example without parameters: 👍 module foo ( input clk_i, input rst_ni, input [7:0] d_i, output logic [7:0] q_o ); Example with parameters: 👍 module foo #( parameter int uns...

The SystemVerilog code below shows the general syntax we use to declare task which pass data by reference. task <return_type> <name> (ref <argument>); // task code endtask : <name> As we can see from this, when we want to pass a parameter by reference rather than value then we ...
I get no syntax errors, but when I try to run the RTL Analysis, I get the error: [Synth 8-36] 'IW' is not declared ["/path/to/file.v":##] The code is pretty simple: module AX #( parameter NBII = 10 , parameter NBFI = 0 , parameter NBIO = 16 , parameter NBFO = 2...
