Hi,
How 2nd point is different than the 1st one ?
- The same signal is driven and sampled at the same time.
=> To avoid this race condition, a clocking block in interface is used as it provides an input and output skews to sample and drive, respectively. - Race condition between testbench and design.
=> The program block is used to avoid this race, as module executes on an active region, while program block executes in reactive region.
