I'm facing around 100 errors related to combinatorial loops when bitstreaming. The signals causing these errors are addr_121f, addr_store_1_f, and add...

I have read the chapter on scheduling semantics and can understand what the standard is saying. As the standard says, the simulator can suspend an up...

I have stumbled upon an unusual behavior in verilog. I have this very simple module test `timescale 1ns / 1ps module test ( input clk, input ...

I am trying to create a simple module with tilelink client connected to modules output. How to do it? Have been trying to figure it out for 20 hours a...

I tried to write my own true dual-port memory module, hoping that it would infer as a BRAM: module dp_async_ram (clk, rst, rd0, rd1, wr0, wr1, in1, i...

I have a test bench module such as below: `timescale 1ns / 1ps module RandomDelay_tb; reg t_clk=1; reg t_rst_n=1; reg t_input_signal = 1;...

I am writing verilog code for 4 bit adder subtractor. I am using structural design. At first I have written verilog code for 1 bit full adder. Then I ...

I'm trying to write a code to check for even/odd parity in Verilog. `timescale 1ns / 1ps module ParityChecker( input [7:0] bitt, output reg ans ); i...

i want to find a single max value for an input signal that has 1000 decimal values that is read from a memory once every Positive clk edge. i did the...
