Interview Questions on Blocking and Nonblocking Assignments

WebbThe nonblocking assignment does not block other Verilog statements from being evaluated. Execution of nonblocking assignments can be viewed as a two-step process: 1. Evaluate the RHS of nonblocking statements at the beginning of the time step. 2. Update the LHS of nonblocking statements at the end of the time step. Webb3 dec. 2014 · 1 Answer.
