3.1i Modular Design - In active module implementation, ngdanno with ngm (non -module) may disconnect port net
説明
Keywords: Modular, diconnect, port
Urgency: Standard
General Description: This applies to simulation in the active module implementation phase, using the NGM file and *not* the -module option (that is, simulating with the top-level wrapper). If a module input port drives a buffer, which then drives logic inside the module, ngdanno may delete the buffer and disconnect the module internals from the net in the top-level wrapper.
The work around is to back annotate without the NGM file.
ソリューション
This problem will be fixed in the first 3.1i quarterly release, currently scheduled for August, 2000.
