Abstract

A program is disclosed that takes non-human readable Graphics Language 1 (GL1) and converts it into editable prewires used in the VLSI Interactive Design Automatization System (VIDAS) methodology.

Creating Prewires from Graphics Language 1 for the VLSI Interactive
Design Automatization System Tool Methodology

      A program is disclosed that takes non-human readable Graphics
Language 1 (GL1) and converts it into editable prewires used in the
VLSI Interactive Design Automatization System (VIDAS) methodology.

      The program introduced is Gl12prew.  Gl12prew takes GL1 as its
input and outputs prewires in the ASCII virtual in-core model format
(VIM) used by VIDAS.  These prewires can be edited by ASCII text
editors or VIM graphical editors such as vigr.

The binary representation of the wire in the Figure is not human
readable.

      Gl12prew will generate the following prewires that will be
placed in the VIM.  These prewires can be edited with ASCII text
editors or VIM editing tools.
  PREWIRE CAA_TEST(0) M2   0  0 101  1
  PREWIRE CAA_TEST(0) M1 100  0   1 21
  PREWIRE CAA_TEST(0) M2 100 20 126 21

      Chip integrators now have the choice of adjusting wires through
the use of a text editor or through a VIM graphical editor.  The two
editing options allow the chip integrator greater flexibility...
