Strange numbers in Virtuoso 6.1.5

JulianJ

 Hello,

I am seeing some strange number errors in Virtuoso 6.1.5.

In the ADE, I type  "1p" as the value for a variable and when set it appears as "1e122", "100f" becomes "1e155", "1f" becomes "1e155".

A similar error is also appearing on the drain diffusion area calculated on the FETs I am placing in my schematics, with the calculated area being displayed and netlisted as "480e155", when I think it should be "480f".

 I tried upgrading my instalation from  IC6.1.5-64b.500.1 to IC6.1.5-64b.500.9, but still have the same problem.

 Any help appreciated.

  • Hi, Is there any news on this? I suffer from the same problem. However, it just randomly appears. I use a supported platform (CentOS 6, 64 bit). If I enter aelSuffixNotation(1e-12) I also get "1e122" for example, but as said this just happens from out of nowhere. Is there any disadvantage running virtuoso in 32 bit? (for example, a famous 2GB memory limit, slower simulations, ...). If yes, then that's not really a fix ... Thanks!
