Mapping EDIF file from OrCAD Capture 9.2

Problem: Can't get Library Mapping funtion to work

Description: Design for mixed signal ASIC captured and simulated in OrCAD 9.2. Need to emulate logic in a MAXII CPLD. EDIF 2.0.0 netlist generated from OrCAD needs to be mapped for use in Quartus II 8.1

Design Entry Tool: OrCAD 9.2

Output: EDIF 2.0.0 netlist

Synthesis / Fitter: Quartus II 8.1

Design file: CNTR.EDN

Type: EDIF File

Design entry/synthesis tool: Custom

Library Mapping File Name: sta-alt1.lmf

First attempt to compile following edit of sta-alt1.lmf alway gives the warning

Warning: Can't locate Library Mapping File

Any following attempts to compile do not get the warning

The following errors are always generated:

Error: Node instance "U1" instantiates undefined entity "NA2"

Error: Node instance "U2" instantiates undefined entity "I"

Error: Node instance "U3" instantiates undefined entity "NA2"

Error: Node instance "U4" instantiates undefined entity "NA2"

this is the library mapping file:

LIBRARY sta-alt1

    Are you adding the .lmf as a custom file? This is done under Assignments -> EDA -> Design Entry, than choose Custom and add the .lmf below.

    Yes I am adding as a custom file with the method you described.

    Tool name: Custom

    Format: EDIF

    Signal Names

    VCC: VCC

    GND: GND

    Library Mapping File

    File name: ../../altera/81/quartus/lmf/sta-alt1.lmf

    I have also tried modifiying syntax in the .lmf to match what is prescribed in the help files and also matching that of existing .lmf files included in the Quartus installed lmf library

    I have verified that if I manually replace NA2 with nand2 and I with inv, that the EDIF file will compile synthesize, fit and program correclty. It's just a matter of getting this mapping to work

    Hi,

    did you still get this message "Warning: Can't locate Library Mapping File" ?

    Kind regards

    I still get the message once any time I edit either the design file or the .lmf file. Any attempts to compile following the first warning do not generate another warning.

    I have tried locating the custom .lmf in the lmf directory created when Quartus II was installed ... didn't help.

    Could this mean that for whatever reason, the .lmf is never being found?

    Can anyone see something wrong with the EDIF file that could cause this behavior?

    People are sucessfully using Library Mapping every day are they not?

    Hi deepblue,

    good news, I could run your testcase sucessfully. I have the project attached.

    Look under settings -> EDA tool settings how I define the path to your lmf.

    Have fun

    GPK,

    Thank-you very much for taking the time to confirm that library mapping with my EDIF files can be done. I opened the project you sent me and indeed library mapping worked.

    In an attempt to figure out what I was missing, I modified my existing project to match your settings. I put the design file and lmf in an identical hiearchy ... same problem as before, didn't work.

    Then I made a brand new project, same files, same hiearchy, same project settings, and direct to lmf file. I worked properly, just as your project did.

    This is a little concerning to me because it means there is some aspect of the project settings I don't know how to control.

    Any Ideas?

    Is there some cache that needs clearing?

    Thanks,

    Eric

    Hi Eric,

    sometimes Quartus has problems with his own database located the "db" folder.

    In case of some strange behaviour I delete this db folder and run the project again.

    Often this helps.

    Kind regards
