Problem generating cdb views with make_cdb Version 6.1

Hi ,

I have problem generating cdb views. There are multiple Warnings:

1. WARNING:(SI-2167) The -synlib option of the generate_cell_lib command is
obsolete. To load Synopsys .lib files, use the read_dotlib command before
generate_cell_lib.

I have added the read_dotlib command before generate_cell_lib but warining still appears.

2. Some warnings comping from the Spice logic file used -- I assume these can be ignored

3.And finally the cdb views are not generated with the following status:

==> ERROR: Memory allocation failed <TECHLIB-253>.
ERROR:(SI-0511) Signal 6 Caught. [make_cdb]
Runtime : 217.46u 7585.2s 36230w
Heap Growth : 31603.3MB

Please help and let me know if any additional info is needed.

Moved to the Digital Implementation Forum because it's more likely to get an answer there.

Andrew.

Hi Anna,
For the memory crash (#3), run make_cdb -64.
For the synlib warning (#1), did you remove that command from your command file?

Hi Kari,
-64 option is on. It does not help.
I have removed the -synlib and add the read_dotlib. But I see errors:

Looks like you're missing the -cell_list parameter of generate_cell_lib.

Afer running my script within make_cdb 7.1, I have the follow error:
process_constraint: Finished in 0 seconds
Assertion `_r >= 0.0' failed
cmfatal: ERROR: Stopped in file resrdx.cxx line 210
ERROR:(E_FATAL_ERROR) The program has a fatal error and is being terminated.
Fix the ERROR and WARNING messages in the log file and re-run [cmfatal]
ERROR:(SI-0515) Internal Error : Cannot continue execution .. exiting [make_cdb]
Is this a bug in the tool?
