WebNov 29, 2012 · Yes, you should name your begin-end block and then use disable statement like this: always @ (posedge clk_i or posedge rst_i) begin : block_to_disable if (rst_i) begin // Do stuff disable block_to_disable; end // Do stuff end Though, this is probably non-synthesizable, so you can do such tricks only in simulation (testbenches, etc.). Share WebApr 10, 2024 · From my knowledge, this is not recommended, for two reasons: 1. If the driver has a bug, then the design and the scoreboard will get two different versions of supposedly the same input. 2. If this testbench were to be integrated at a higher level environment, then the scoreboard would not work - in such higher level env, the decoder inputs ...

WebA repeat loop in Verilog will repeat a block of code some defined number of times. It is very similar to a for loop, except that a repeat loop’s index can never be used inside the loop. Repeat loops just blindly run the code as many times as you specify. Repeat Loops can be used synthesizable code, but be careful with them!. WebThe verilog assign statement is typically used to continuously drive a signal of wire datatype and gets synthesized as combinational logic.
