http://www.sunburst-design.com/papers/CummingsSNUG2016AUS_VerificationTimingTesting.pdf WebA single time slot is divided into multiple regions where events can be scheduled. This event scheduling supports obtaining clear and predictable interactions that provide for the ordering of particular types of execution. This allows properties and checkers to sample data when the design under test is in a stable state.
WebMay 4, 2024 · I tried to simplify the file and extract a minimal non-working example. The file looks like this: package test_pkg; task wait (ref logic clock, int cycl_num); for (int k = 0; k < cycl_num; k++) begin @ (posedge clock); end endtask : wait endpackage So, simple package with one task. Running xrun test/test_pkg.sv: Lots of errors here. WebWhen the associated signal is a variable, the procedural assignment assigns a new value to the variable, and the variable shall hold that value until another assignment occurs (either from a drive to a clocking block output or another procedural assignment).
