    PAL simulation Reply

    I need to simulate a PAL10H8 (included in DIG_PAL.OLB library. Parts in PLD.OLBlibrary can not be simulated), but I have got this error:

    "ERROR -- Subcircuit PAL10H8 used by X_U1 is undefined"

    How can I simulate with that part? Its implementation type is 'PSpice model', and I have a correct JED file... This is part of the .out file:

    X_U1         B3 B0 B1 B2 ...

    +  ... $G_DPWR $G_DGND PAL10H8 PARAMS: 

    + IO_LEVEL=0 MNTYMXDLY=0 TEXT: JEDEC_FILE="bcd7seg.jed" 

    What is the problem? Any idea?

     Thanks in advance

    As a start, I recommend that you try the FULL path and filename for your JEDEC file so that the simulator can find it when running. If you are running in "Lite", unlicensed, mode the simulator may not work with this type of part.

    IF the full path + name does not work, ZIP the output file and attach it to the forum since there may be some "gems" in there that identify the real issue.

    I agree with Oldmouldy, the problem seems to be with missing model "PAL10H8". Please check if you have nom.lib added in your simulation profile. If you are running with Lite version of PSpice, you may not be able to simulate this part.

    (SOLVED) Re: PAL simulation Reply

    Thank you sir because your interest, but I'm using a licensed 16.2 version.

    I think the path is not a problem, but the model, as you suggested:

    ERROR -- Model IO_STM used by U_DSTM1 is undefined

    ERROR -- Subcircuit PAL10H8 used by X_U1 is undefined

     

    The reason is IO_STM is defined in dig_io.lib, not in dig_pal.lib (which includes PAL10H8)... But dig_io.lib it is not included in nom.lib. Ok, after included to my design, only one error result:

    ERROR -- Subcircuit PAL10H8 used by X_U1 is undefined  

    Finally, I found it in dig_pal.lib. Added and no error result.

    The question is: Why I could see PAL10H8 symbol with the simulable-part icon in the parts browser of Capture from the start?... It made waste my time...

    Thank you all for all
