iPDK from TSMC 28nm pcell problems

Luc Laeveren

Hi,

We're having difficulties with the usage of the two TMSC 28nm iPDK's in Cadence:

iPDK_CRN28HPL_v0.3_2a_20110715_all.tar.gz and t-n28-cr-sp-003-w1_1_0b_20110620.zip

During instantiating of a PCELL in layout XL we get following warning:
*WARNING* (DB-220704): The Pcell super master: tsmcN28/nch_mac/layout is not a SKILL super master.The usage of non-SKILL Pcells in Virtuoso is not a supported feature.

Though it's only a warning, no layout is created, only a red square is visible on the layout screen.

The installation went without any problem and we're using the exact same tool version as TSMC states in the Releasenotes;

Program:        @(#)$CDS: virtuoso version 6.1.4-64b 08/02/2010 00:21 (sjfnl002) $
Sub version:        sub-version  IC6.1.4-64b.500.6  (64-bit addresses)

I presume this has something to do with the phycells vs skill pcells? Do I need additional installation scripts or tools?

    Dear Quek,

    Thanks for the answer. During installation I can only select PYCELL.

    *Available PDK types:
    ************** Please choose PDK type  ***********************
       1 - PyCell             : support multi-platform
                                Cadence/Synopsys/SpringSoft/Magma/Mentor
    ==============================================================
    Please enter your choice:

    Do I need to do the switch later on? Or within Virtuoso?

    Kind regards, luc
