"migration" step fail #25

Closed PiyushSaini97 closed 3 years ago

PiyushSaini97 commented 3 years ago

Hi-

I have been trying to synthesize a basic full adder using qflow. However, when I run the software, the process encounters an error at "migration" step. You can see in the attached image error_migration

I don't understand what the error is about. None of the variables I used contain a number or special character. I'm also attaching the verilog code I'm trying to synthesize. fa

Please help. Thank you.

Regards, Piyush

Hello, so I had the exact same error and tried some debugging through the past few days but to no avail.

It seems like a tcsh syntax error but i couldn't track it down, the changes i made to both the qflow.sh and qflow.sh.in weren't reflected also. P01

I've taken a few snippets of the debugging process and hope it sheds some light. I will try to roll back to an older version and see if that's stable. I've used map9v3.v file as instructed in the tutorial so I haven't included that. I also deleted and reinstalled Magic and Qflow a couple of times over from the git repo through the GNU Autoconf.

For those who don't know, the following files can be found in qflow/scripts and the exec file in the project root directory.

QflowShellLn394 P02

QflowShellLn880 P03

ExecScriptUpdated P04

QflowManagerLn1539 P05

QflowManagerLn3239 P06

The _magicdb.sh was also checked and added a test line but it wasn't reflected. P07

Thanks for your time

You have to make the changes to all four magic files. Let me know if this works.

Yes, i found the post right after i commented here, but even after changing the files, it didn't work. tried gedit , vim, and chmod to make it executable for a regular user also but they dint work. Then i attempted a reinstall and that too dint work. I rolled back to an older release and now it's fine, have a few LVS errors with my personal files now need to look into it. Archive used 1.4.90 .

Did editing the shell files work for you? if so how did you do it?

PiyushSaini97 commented 3 years ago

Yes it did work for me. I had to add just an '=' as stated in above post in four files: magic_db.sh, magic_drc.sh, magic_gds.sh and magic_view.sh. You can use "find" option available in gedit to find set techfile ${techdir}/${techfile} and replace it with set techfile=${techdir}/${techfile} in all four files.

Since its working, I'll close the issue now.
