Veriloga中输出出现延迟解决方法 Veriloga建模仿真出现delay的解决 想用verilog建立一contention detector,但建模仿真后出现输出结果有延迟,同事提醒可能时间建立有问题。原代码如下: 下面是仿真结果: 从结果看输出有一定延迟,veriloga理应是理想模型不应该有这样的问题。同事提醒后加入语句bound_step(1n)。解决! debug后仿...

// bound the frequency (this is optional) if (freq > fmax) freq = fmax; if (freq < fmin) freq = fmin; // bound the time step to assure no cycles are skipped $bound_step(0.2/freq); // phase is the integral of the freq modulo 2pi phase = 2*`M_PI*idtmod(freq, 0.0,...
1- Is there a way to display the value of those variables during the analog simulation? I was looking for VerilogA compiler to test my code first but I didn't find, can some one suggest me a website or any information? 2- The statement of @(initial_step), does it mean the command...
Example: $bound_step(10n); 7 PLATFORM APPLICATION NOTE 4 ANALOG MODELING CONSIDERATIONS Good behavioral modeling should consider how the analog simulator will interpret the model and work at the various conditions required, whether it be the circuit, temperature, supply, or process change. If ...
