LOGIC PROGRAMMING
The 10H20EV8/10020EV8 is fully supported
by industry standard (JEDEC compatible)
PLD CAD tools, including Philips
Semiconductors SNAP design software
package. ABEL
and CUPL design
software packages also support the
10H20EV8/10020EV8.
All packages allow Boolean and state
equation entry formats. SNAP, ABEL and
CUPL also accept, as input, schematic
capture format.
10H20EV8/10020EV8 logic designs can also
be generated using the program table entry
format detailed on the following page. 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, F, Q, etc.) is assigned a symbol.
The symbols for TRUE, COMPLEMENT,
INACTIVE, PRESET, etc., are defined below.

NOTES:
1. This is the initial unprogrammed state of all link pairs. It is normally associated with all unused (inactive) AND gates.
2. Any gate (P, D, AP, AR) will be unconditionally inhibited if any one of the I, F or Q link pairs is left intact.
