Question: How can I switch between two voltage source connected to the same node for some time and duration using HSPICE elements. Answer: There are two ways to do this. One is to design a Verilog-A module that can be used as a behavioral switch. Another is to use the HSPICE voltage cont ...
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Question: Is there a test bench showing how to add jitter to the PRBS source? Answer: The attached example contains a sample and hold Verilog-A model which can be used to add jitter to a PRBS source. Care should be taken so that ...
———————————————————————————————— Question: Does HSPICE support encryption of Verilog-A modules? Answer: Beginning with the E-2010.12-SP2 release, HSPICE can encrypt Verilog-A modules. The two methods supported are: 1) 8-Byte encryption 2) 3DES encrypt ...
Question: How can I dump the values of non-electrical Verilog-A variables to the waveform. file? Answer: 1. Set the environment variable HSP_VACOMP_OPTIONS -G at the command prompt (on UNIX/Linux). % setenv HSP_VACOMP_OPTIONS -G 2. Add a .PROBE statement to the top level SPICE netli ...
1. .print will store the simulation output in a special file(*.tr#,*.ac#, etc) for following analysis by waveform. viewer.At the same time, itprints the value in text format (in the ".lis file) for you, so you can checkout the text output format. .probe only store the simu ...
list文件中提示为: **error** call to epvaHDLcgen failed. google不到这样的错误提示,开始也怀疑是lic不全,后来觉得可能出在文件路径上。因为工作文件夹放在My Dropbox下,担心是文件名中的空格的原因。 再打开生成的*.valog文件,发现里面最后一句提示是*pvaE* 'd:/doc/my' file does not exist.。果然就是文件 ...
