General Description:
How do I obtain a simulation with valid outputs from a waveform with uninitialized inputs?

解决方案

In version 2.0, HDL Bencher no longer asks if you would like to initialize all inputs to a known state. Therefore, you must take the following steps to ensure valid outputs in simulation:

1. In Project Navigator, set the simulation run time to 0 ns.

2. In the simulator, force the uninitialized input ports (i.e., GSR or GTS) manually to some known value (such as 0 or 1).

3. Run the testbench.
