Internal Error: SubSystem VPR20KMAIN

Hi All: I've just recently ran into a problem about 65% though the fitter stage of my design: Internal Error: Sub-system: VPR20KMAIN, File: /quartus/fitter/vpr20k/altera_arch_common/altera...

Hi Adrian:

I can't give you that exact error but it was similar if not identical to:

Internal Error: Sub-system: TDC, File: /quartus/tsm/tdc/tdc_accessories_analysis.cpp, Line: 1571

m_edge_domain_data[iedge].m_relaxed_domain_slack_ratio < JUST_BELOW_HUGE_FLOAT

Stack Trace:

0x59E2 : _Dinkum_std::hash_compare<TDC_PATH_TIMING *,_Dinkum_std::less<TDC_PATH_TIMING *> >::operator() + 0x3B62 (TSM_TDC)

End-trace

This particular error came from a co-worker that was experiencing a similar issue.

Like I said before it seems to only occur when the Cisco VPN was active. I have since upgraded the VPN client from 4.8 to 5.0 and now the problem seems to have gone away.

I've told my co-worker to also upgrade his vpn client, in the hopes that this solve the issue.

Thanks for the assistance!

Pete
