Philips Semiconductors Programmable Logic Devices

CMOS programmable multi-function PLD

(42 Ã 105 Ã 12)

Product specification

PLC42VA12

LOGIC PROGRAMMING

The PLC42VA12 is fully supported by

industry standard (JEDEC compatible) PLD

CAD tools, including Philips Semiconductors

SNAP design software package. ABELâ¢ and

CUPLâ¢ design software packages also

support the PLC42VA12 architecture.

All packages allow Boolean and state

equation entry formats. SNAP, ABEL and

CUPL also accept, as input, schematic

capture format.

LOGIC IMPLEMENTATION

âANDâ ARRAY â (I), (B), (Qp)

I, B, Q

PLC42VA12 logic designs can also be

generated using the program table entry

format, which is detailed on the following

pages. This program table entry format is

supported by SNAP only.

To implement the desired logic functions, the

state of each logic variable from logic

equations (I, B, O, P, etc.) is assigned a

symbol. The symbols for TRUE,

COMPLEMENT, INACTIVE, PRESET, etc.,

are defined below. Symbols for OMC

I, B, Q

configuration have been previously defined in

the Architectural Options section.
