Title: Real numbers multiplication
Post by ihabraad on Feb 28^th, 2007, 1:58pm

Verilog question (Tripoli – Lebanon)
Real numbers multiplication
Hi;

I nead a help for a verilog simulation program:

I am trying to do a real numbers multiplier in verilog simulation code using ModelSim simulator (without schematic).
The Problem is that Verilog doesn’t accept to define an input as real (register) and when I try to use intermediate real registers before multiplying and put the result also in a real register; verilog around them to integers!!!! L
I am very sad…. :’-( Plz any help?

In Verilog you can use a 64-bit bus to pass real-valued signals. Then you use real2bits() to convert the real number into the 64 bits, and bits2real() to convert back.
