TINA/Spice/CSD18563Q5A: PSPICE model for CSD18563Q5A

CSD18563Q5A: Spice model for spectre in Cadence Virtuoso

Part Number: CSD18563Q5A

Hi !

I am unable to simulate the CSD18563Q5A spice model (CSD18563Q5A.lib) available online. I am using the spectre simulator in Cadence Virtuoso's Analog design Environment (ADE).

Receive the following errors while simulating,

Warning from spectre in `cgs', during circuit read-in.
    WARNING (SFE-1772): "./CSD18563Q5A.lib" 107: Found an unquoted ambiguous expression that contains the `*' character. Therefore, the part of the expression after `{-1e15*v' will be treated as a comment.
Warning from spectre in `cgd', during circuit read-in.
    WARNING (SFE-1772): "./CSD18563Q5A.lib" 179: Found an unquoted ambiguous expression that contains the `*' character. Therefore, the part of the expression after `{-1e15*v' will be treated as a comment.

Error found by spectre in `CSD18563Q5A', during circuit read-in.
    ERROR (SFE-874): "./CSD18563Q5A.lib" 255: 21: Unexpected numeric value "11.00e-3". Expected end of file or end of line. Cannot run the simulation because of syntax error. Correct the error and rerun the simulation.
    ERROR (SFE-874): "./CSD18563Q5A.lib" 256: 21: Unexpected numeric value "5.0e-5". Expected end of file or end of line. Cannot run the simulation because of syntax error. Correct the error and rerun the simulation.

Can you please share a spectre compliant spice/spectre model ?

Regards,
Bhushan

    Hi Bhushan,

    Thanks for your interest in TI FETs. It appears that there are some syntax differences when using our PSpice models with Cadence Virtuoso's Analog Design Environment (ADE). I have reached out to a colleague who is more knowledgeable on this subject and will follow up as soon as I have more information. Please look for a response later today or tomorrow.
