Wait for a specific delay

 Hi!

The issue you're seeing is the fact that you're using a uint (or whichever numerical type) and a time denominator (ms here) to specify the delay, which basically takes a uint. The time type in my view is just a special numerical type. So you can do two things:

1) Use a var (or struct member) of type time and gen that, feeding it to delay() without the time denominator.

2) If the ms granularity is of imporance, do something like this:

  var one_ms : time = 1 ms;

  gen time_delay;

  time_delay *= one_ms; //multiply with 1 ms granularity...

  wait delay(time_delay);

I'd say that should sort things out. Let me know if there's another issue (you can reach me directly by picking my first name at cadence.com).

Good luck,

I'd add a small word of warning to this topic: asking for a "wait delay" does have a performance impact, because a callback has to be registered for the delay. If you only call the delay fairly infrequently it should not be a problem, but if you call wait delay too often (e.g. on every clock egde) then the simulation performance can be impacted.

So use it with care, and if possible use some event-based delay mechanism rather than time-based.
