WebThe variable assigment in VHDL (with :=) takes place immediately. To get the same behaviour in Verilog, you have to use the blocking assignment with = instead of the non-blocking one ( <= ). In your example, blocking assigments for variable z are required because your code checks the new value of z immediately after assigning it. WebAlgorithm. The algorithm operates as follows: Suppose the original number to be converted is stored in a register that is n bits wide. Reserve a scratch space wide enough to hold …
