AR# 522
VST/386+ Gives "Terminal Error - Incompatible Version of MODEL Files."
描述
When running SIMULATE (or hitting the Simulate button) with the OrCAD VST/386+ versions prior to 1.20, the program returns the following error message:
"Terminal Error - Incompatable Version of MODEL Files."
解决方案
This is due to the fact that OrCAD has modified it's simulation library format in VST v1.20. The Unified Libraries released with XACT 5 (as well as libraries prior to XACT 5) are compiled in an older VST library format. The new library format is necessary in order for OrCAD to facilitate board level simulation. The error message is correct, the MODEL libraries do need to be updated in order to use VST386+ v1.20.
For the XACT 5 Unified Libraries, obtain a copy of ORCSRC.ZIP from either the software help directory on the Xilinx BBS, or from the <Drive>:\XBBS\swhelp directory of the XACT 5.1 CD. Unzip the file using the command:
PKUNZIP -D ORCSRC.ZIP
Each of the directories (i.e. XC2000, XC3000, XC4000, & XC7000) will contain the necessary '.DSF' files. Use these files to compile the OrCAD libraries, and use them in place of the MODEL.DAT & MODEL.NDX files that came with the XACT 5.0 or XACT 5.1 Unified Libraries.
The .DSF files for the non-Unified Libraries can be found in the file ORLIBSRC.ZIP on the Xilinx BBS.
NOTE: The files in ORCSRC.ZIP are uncompiled text files. They must be compiled using OrCADs tools in order to make valid MODEL.NDX and MODEL.DAT files (both binary) for use in the OrCAD VST386+ v1.20 simulator. To compile these .dsf files from DOS, do the following: modelpro library.dsf This should update the MODEL.DAT and MODEL.NDX files.
Note that Xilinx has updated the simulation libraries for VST 386+ version 1.2x with the 5.2/6.0 release of XACTstep.
