Re: ERROR: @E Simulation failed: SIGSEGV.

Hey @hongquan18196,


Your issue looks extremely similar to this one: @E Simulation failed: SIGSEGV. ERROR


Can you try some of the debugging steps @nupurs recommends in their reply?


There are a couple more hints on how to debug SIGSEGV errors in this thread: How can I trace SIGSEGV Error in C simulation?
