Title: Charge Sensitive Amplifier RNM Post by Dimitri Cern on Mar 3rd, 2015, 6:56am Good morning everybody, I am a new user and I knew about the forum from the book the designer's guide to Verilog-Ams. In our project we just decided to move toward a system level Verification using Real Number Modelling for the Analog Blocks. I had some problems in modelling the Charge Sensitive Preamplifier. Basically I modelled it in RNM considering the transfer function of the CSA. The behavioral model works fine but I have a problem with the input port. My input port is a wreal and is fed by a current pulse (electrical signal). The problem comes when the conversion between electrical to wreal signal is made. I'm not able to model the input current in such a way I could get a proper value of the voltage at the output. I checked about defining a new discipline but I didn't get how to fix it. Any suggestions? Thanks and Regards Dimitri |
