Quote:1. If ourput loading is too big , this means you don't have enough strength.
I removed device and leaved only PADs as stimuli charges. In this case everything was correct.
The simulation settings in both cases were the same:
Simulator:
UltrasimSimulation Mode:
Digital FastSpeed Dial:
8Analog:
DigitalMOS method:
Digital PWL nonlinear CDiode method:
Analog table Quote:2. Frequency is too high for built-in connect module to catch for example the default rise time is 1ns in connect rule .
Pulse duration is 130ns
Quote:In AMS-ADE Setup-> Connect Rules .. you can customerize the CR parameter based on the default CR .
I didn't find this option. For my simulations I use Hierarchy Editor AMS Plug-in. Connect Rules settings I can get only when start up the simulation. And only settings that I can change there is connect library, connect cell and connect view.
Quote:BTW, bound_step is to set simulation maxstep of this module to be less than 1/Frequency .
bound_step I specified to be 1ns.
I'm afraid that it's just simulator bug.
Thanks one more time Zhong.
