Cant find PTAP contact in TSMC 0.18u deep technology (NCSU_TechLib_tsmc02d)

rajrevanth61

 Hello all,

i was designing a layout using the tsmc 0.18u deep technology(NCSU_TechLib_tsmc02d), but I am not able to find the PTAP contact, when i go in the contact options. These are the only these contacts available ((M1_poly, M1_N, M1_P, M2_M1, M3_M2, M4_M3, M5_M4, M6_M5, NTAP).

can i use M1_P instead of ptap?

Can i create my own contacts and add it to the library? If yes, then how to do it?

Please help me

Thanks

    Hi rajrevanth

    As this is a pdk related issue, it would be best to refer to the pdk documentation or to contact TSMC customer support. Perhaps you can try the following:

    a. Check if there is any "ptap" cell in the technology directory. Is it supposed to be added using "Create->Instance"
    b. Try M1_P to see if it works (I am not sure, just guessing)

    You can create your own vias as follows:
    a. In CIW, go to "Tools->Technology File Manager"
    b. Dump out the techfile in ascii format
    c. Modify the techfile
    d. Load the techfile and save it using Technology File Manager.

    Best regards
    Quek
