Verilog - initializing register to high impedance? - Stack Overflow
Webassign (highz1, strong0) scl = device0_scl_value; assign (highz1, strong0) scl = device1_scl_value; This is is not just nice because it’s a concise way of having the simulator figure out the interactions between devices on the bus, but it does so in a way that structurally mirrors how the circuits work. Web* * data_input - data for writing, latched in when wr_enable is highz0 * * data_output - data for reading, comes available sometime * *few clocks* after rd_enable and address is presented on bus * * rst_n - start init ram process * * rd_enable - read enable, on clk posedge haddr will be latched in, openpay by bbva
