HSPICE concluding before running through .alter statements

  1. gieselle
    Hello Everyone,

    I have a simulation test bench that alters through pvt corners. I've been using the same simulation setup before but it is not working in my new project. What happens is that HSPICE runs my .title corner and concludes it but finishes before going through any other corners. what I have is:

    .title tt
    .lib 'path to the model file' tt
    .temp 25

    .alter ff
    .del lib tt
    .lib 'path to the model file' ff
    .temp 125

    Any ideas how I can fix this or what can be the cause of this? I have to add that I am using the model file in another simulation and it is working fine.
