WebMar 17, 2024 · If your signal changes at the rising edge of the clock, the sampled_data will hold the value before the update. Now for the outputs what is delayed is the sampling moment not the signal always @ (posedge clk) begin #1; tx_driver_cb.data <= data; end The data is sampled slightly after the clock, so it samples the updated value.
