Both resets are asynchronous. You cannot have a synchronous reset in a latch because there is no clock. The always_latch construct in your example … WebHowever, for low speed buses routed on PCBs, there is another solution: update outputs on the negative clock edge, and latch inputs on the positive edge. That way, there is an entire half clock cycle for the signal to stabilize before it will be read, and slowing down the clock gives more time for outputs to stabilize. great northern windows bend oregon

Therefore latches are volatile memory devices, and can store one bit of data for as long as the device is powered. As the name suggests, latches are used to "latch onto" information and hold in place.
