WebSimply put, a clocking block encapsulates a bunch of signals that share a common clock. Hence declaring a clocking block inside an interface can help save the amount of code required to connect to the testbench and may help save time during development. Signal directions inside a clocking block are with respect to the testbench and not the DUT. WebThere are the following two solutions to avoid race conditions. Mutual exclusion Synchronize the process In order to prevent the race conditions, one should ensure that only one process can access the shared data at a time. It is the main reason why we need to synchronize the processes. Another solution to avoid race condition is mutual exclusion.
