MEN2XNF8 5.x: Could not find a registered simulation model with label: 'xc____'
描述
Keywords: men2xnf8, simulation, label, model
Urgency: Standard
General Description:
After retargeting a design from one device family to another, Men2XNF8 (during ENWrite) gives the warning below, which reflects the family FROM which the design was targeted. The warning in this example reflects a design that was targeted from the XC3000 family.
// Warning: Instance: '/RETARGETED/SYMBOL' // Could not find a registered simulation model with label: 'xc3000' // NULL model will be inserted. (from: Analysis/Digital Simulation Utilities/Dsim 85)
ENWrite (Mentor's EDIF netlister) uses an XNF viewpoint to determine which device family it should target. Changing the library references in a design does nothing to its viewpoints, so the XNF viewpoint still reflects the old device family. However, the new library elements in the design expect to see a reference to the new device family; thus the warning message.
解决方案
Delete the XNF viewpoint, then run Men2XNF8 again. This time, Men2XNF8 will see that the viewpoint does not exist, and will recreate it for the correct library.
