WebAlways blocks are called procedural block and it's a very useful constructs in verilog design. This tutorial explains how multiple always blocks are handled ... WebDec 18, 2014 · An array of 16 floating point elements: real delay [0:15];. Within the always block, a wait statement is needed to allow the delay values to be populated. Because it is a clock, I suggest adding a condition checker to terminate the simulation if it fails. This safeguard is to catch 0-time infinite loops while the simulation is running.

WebAug 21, 2016 · Thanks. If you want dealys, you need to call a task. function int f (bit a); #1; // ILLEGAL!!!! return ! a; endfunction Function 'f' has illegal use of delay or synchronization The uses can be wait, delay, clocking block assign, fork -join and other task calls with delays.
