Abstract

This article describes the LMOD Browse (logic model browse) program, a program to interactively browse digital logic designs using graphics. Features incorporated in the LMOD-Browse program are: Interactive browsing of several "cross reference" files to permit the user to select blocks by name regardless of logic partition (e.g., chip, module, etc.). Use of a System Reference File to tie together all the "cross reference" files for a part. Capability to specify the number of levels forward and the number of levels back to be drawn, for each block specified. Capability of zooming an indefinite number of times. Capability of scrolling using a graphic tablet. Allowing the user to specify block and character size, a magnification factor, and an x-y translation.

LMOD Browse Program

This article describes the LMOD Browse (logic model browse) program, a program to interactively browse digital logic designs using graphics.

Features incorporated in the LMOD-Browse program are: Interactive browsing of several "cross reference" files

to permit the user to select blocks by name regardless of

logic partition (e.g., chip, module, etc.).

Use of a System Reference File to tie together all the

"cross reference" files for a part.

Capability to specify the number of levels forward and the

number of levels back to be drawn, for each block specified.

Capability of zooming an indefinite number of times.

Capability of scrolling using a graphic tablet.

Allowing the user to specify block and character size, a

magnification factor, and an x-y translation.

Supporting the use of APL expressions within commands.

Use of the light pen to delete fields from the screen.

The error handling portions of the program:

highlight fields erroneously entered,

position the cursor under the first erroneous

character, sound the alarm, provide on-line

help (through use of the PF1 key) while leaving

the erroneous field on the screen, and supply

the default values when fields are deleted.
