Witryna14 cze 2024 · What you are asking for does not make any sense. If it a signal never can change, then it must be a constant. With the example you show, a1 might fail - there is a race condition between a and not_a.a2 is deferred assertion - it takes care of the race and will never fail. But the problem with both these assertions is that if a changes at …

Figure 3.1 describes the basics of an immediate assertion. It is so called because it executes immediately at the time it is encountered in the procedural code. It does not wait for the ‘next clock edge’ to fire itself. medwork filarowaWitrynaA clock tick is an atomic moment in time and a clock ticks only once at any simulation time. The clock can actually be a single signal, a gated clock (e.g. (clk && GatingSig)) or other more complex expressions. When monitoring asynchronous signals, a simulation time step corresponds to a clock tick. med work hürthWitrynaUntil now in previous articles, simple boolean expressions were checked on every clock edge.But sequential checks take several clock cycles to complete and the time delay is specified by ## sign. ## Operator.
