Use verilog function to define the width of a multi-bit port, Computer Engineering

Assignment Help:

Can I use a Verilog function to define the width of a multi-bit port, wire, or reg type?

Width  elements  of  ports,  wire  or  reg  declarations  require  a  constant  in  both  LSB and  MSB  . Before  Verilog  2001,  it's  a  syntax  error  to  specify  a  function  call  to  evaluate  the  value  of  these widths. For instance, the below code is erroneous before Verilog 2001 version.

reg [ get_high(val1:vla2) : get_low (val3:val4)] reg1;

In the above illustration, get_high and get_low are both function calls of evaluating a constant result for MSB and LSB correspondingly. However, Verilog-2001 allows the use of a function call to evaluate LSB or MSB of a width declaration.
