NCVHDL simulation error

Jinesh K B

Sir, am getting this error when trying to elaborate the design

[root@localhost simulation]# ncelab WORK.trial:trial_rtl

  • These are not errors, they are warnings; the *W indicates the severity and will be one of I (Information), W (Warning), E (Error, can continue) or F (Fatal, must exit immediately). I suspect you're seeing these because you're running as the same user ID as the tool was installed as. In fact it looks like you're running as root, which would be a very risky thing to do, it's always best to use a regular user-level account for everything in Linux. You are also running an extremely old Incisive version, Cadence stopped supporting 10.20 years ago :) I strongly recommend that you install a newer and supported version like 14.10.
  • Thanks for your reply sir. I want to use memory modules in my project (to store intermediate image datas),is there inbuilt memory IP cores available for users, how to use them. I searched but didn't get any idea about this.
