The VTVT Group has developed a  standard-cell library   targeting   the   TSMC-0.25um,  2.5-volt  CMOS  process available  via MOSIS. The  library   can be   used   with Synopsys synthesis tools and the Cadence Silicon Ensemble Place/Route tool. All of the  cells  can be  viewed  and edited  using  the  Cadence Virtuoso layout editor. The cell library requires NCSU design kit or other kits that follow MOSIS design rules. Since MOSIS DEEP design rules are used for our cell library, the NCSU design kit has been modifed slightly and is included in our distribution.

In this Release 2 of the VTVT Standard Cell library, which was released on November 1, 2003, we made the following addition and modification to the Release 1:

• Additional cells. The Release 2 contains 83 cells, compared with 36 in Release 1.
• Additional modification to the NCSU design rule check file. Now MOSIS's wide-metal rule is implemented.

The package for our cell  library includes:

• layouts of primitive cells
• Synopsys synthesis (.db) and VHDL simulation libraries
• LEF files for the PNR tool
• README file and a documentation for modification of the NCSU kit
• Other documentation, including the place and route flow we used to test the library.

List of Cells Distributed (Release 2, November 1, 2003):

• Combinational cells:
  • Inverters:  inv_1, inv_2, inv_4 (the last digit denotes the drive strength.)
