WebVHDL: counter that only counts when there is single-shot event Most counter examples in VHDL are repetitive counters - they will cycle through the counting cycle unless told otherwise. What I need is a counter that starts counting when there is a single-shot pulse, and then doesn't count again unless there is another pulse. General Discussion Like WebCAUSE: In a VHDL Design File at the specified location, you used a Case Statement as a Register Inference. However, a Case Statement cannot contain a condition that specifies that the statement be executed at the rising or falling of an edge or at the occurrence of an event; as a result, you cannot use the Case Statement to infer a register. ok jaanu with english subtitles watch online
