  • TCL based assertion for connectivity check

    Hi, I am using ncsim and i wish to check connectivity between two nets in RTL/netlist using tcl. I remember there being someway where using tcl input file i could specify two nets which could be tested for connectivity. ex: -src net1 -dst net2 on a change of net1 check net2 value is equal to net1 value...

  • Re: forcing the creation of a vcd file

    Hi Stephen, Thanks for the reply. I strictly need it to be in VCD format as I am passing this file to analog team so that they can use is to see if there is any problem in the signal change and in the signal itself. Also we use it in the tester to test the chip. If there is any way around to probe the...

  • ncsim without any optimization

    Hi, I want to run my behavioral model using ncsim without any optimization. I look at different option like -linedebug , -access +rwc but none will stop all the optimization like modelsim does with -novopt. Is there any equivalent option is NCSIM? I want to do this because my simulation is giving...

  • vhpi start-of-restart callback

    I'm running a vhpi C++ application. I'm having difficulty getting ncsim to call my start-of-restart function after a restart. Here's my sequence: 1) Start simulation A. I pass the -loadvhpi option to ncsim to load my C++ dlm. 2) Save a snapshot. My vhpi app saves a C++ start-of-restart callback...
