WebVHDL Programme 1ns 1ps company: engineer: create date: 12:42:13 design name: module name: half_adder_b project name: target devices: tool versions: description WebBecause of `timescale 1ns/ 1ps, max precision of 1ps, or .001 ns. So #22.001 will be simulated as 22.001 ns. #22.0001 will be simulated as 22.000 ns; If you want to speed up your simulation, make the resolution lower. Note you can never have a resolution that is lower than the length of the tick though;

WebSep 8, 2024 · @garmin-mjames If I have a timescale of 1ns/1ps, that means that #1 in Verilog will delay for 1ns, but the simulator takes steps at a 1ps resolution. So you can make a #1.001 and it still works. If your resolution is 1ns/1ns, then #1 and #1.001 both resolve to #1. The issue I was facing was that the step was not specified so it defaults to 1s ... WebApr 20, 2024 · Experiment We will design and implement a simple controller of an elevator in a three-story building as in your lab manual for Laboratory No. 6. The elevator has two input bottons or state variables RO and R1 and two state variables Q0 and Q1. Assume that buttons cannot be pressed simultaneously. The elevator controller will use only 4 states ...
