SystemVerilog Concurrent Assertions - ChipVerify

WebMay 2, 2024 · If clock gets delayed more than a delta cycle from clk, you get the "new" value of out_a. A clocking block helps by guaranteeing that you use the sampled value out_a before the the clock edge and removing any skew between clocks. But if you do not plan on doing any gate-level simulation and have made sure all your synchronized clocks … WebApr 3, 2015 · I am new to verilog and having a bit of trouble getting along with it.

Effect of clocking block on uvm driver/monitor

WebMay 19, 2024 · In reply to uvmsd: If at time 0 (or any other time afterward), clk_en && rest is false or unknown (x), your monitor gets into a 0-delay forever loop, which is a hang. You should not mix different clock expressions, just use @ (counter_vif.counter_cb); You could change your clocking block signal directions to 'inout'. WebImmediate assertion example. Below is the simple immediate assertion, always @(posedge clk) assert (a && b); Below is the wave diagram for the above assertion. Condition (a && b) will be checked at every posedge of the clock, failure in the condition leads to an assertion failure.
