Error detected in psf library while writing to file `tran.tran'.

Hi,

This error typically indicates insufficient diskspace but you mentioned that this shouldn't be an issue. Can you share your simulation log (spectre.out)?

Regards,

Hi 

I also facing the same error .Please tell me how to fix this error and i also not have problem with space.

Dear sachin2911,

The error reported in your spectre.out file (SPECTRE-7035) is characteristic of running out of disk space. Please see the troubleshooting article at URL:

https://support.cadence.com/apex/ArticleAttachmentPortal?id=a1Od0000000nbGwEAI&pageName=ArticleContent

I read in your post that disk space did not seem to be an issue in your case. However, you might consider setting the options to monitor available disk space and suspend the simulation until sufficient disk space is available. You can set the threshold at which the simulation will be suspended as well as a feature to automatically restart the simulation. The options can be set through the ADE GUI as detailed at URL:

Spectre Classic Simulator, Spectre APS, Spectre X, and Spectre XPS User Guide -- Running a Simulation - Suspending a Simulation Automatically When Disk Space is Low

I use this feature all the time in ADE Assembler/Explorer as well in prior Cadence ADE tools and it works well to avoid the issue your spectre.out appears to show.

You should also check your disk quota - maybe that has been exceeded (that might be more restricted than the disk space). Take a look at how big the file that was written was and check quotas with the UNIX quota command, maybe.

Also, you're using an 8 year old version of the simulator - using a more recent SPECTRE and IC version would also then enable usage of a newer PSF XL version which supports lossless compression, which will make the output data smaller.
