WebDec 7, 2024 · verilog_spi - A simple verilog implementation of the SPI protocol. I wanted to learn verilog, so I created an own SPI implementation. Goals: Easy to read, easy to understand. WebInput (or inout) signals are sampled at the designated clock event. If an input skew is specified then the signal is sampled at skew time units before the clock event. Similarly, output (or inout) signals are driven skew simulation time units after the corresponding clock event. Input and Output Skew
