PEEL
Array Development Support
Development support for PEEL
Arrays is provided by
ICT and manufacturers of popular development tools. ICT
offers the powerful WinPLACE Development Software (free
to qualified PLD designers). The WinPLACE software
includes an architectural editor, logic compiler, waveform
simulator, documentation utility and a programmer
interface. The WinPLACE editor graphically illustrates and
controls the PEEL
Array
’
s architecture, making the
overall design easy to understand, while allowing the
effectiveness of boolean logic equations, state machine
design and truth table entry. The WinPLACE compiler
performs logic transformation and reduction, making it
possible to specify equations in almost any fashion and fit
the most logic possible in every design. WinPLACE also
provides a multi-level logic simulator allowing external and
internal signals to be simulated and analyzed via a
waveform display.(See Figure 12, Figure 13 and Figure 14)

PEEL
Array development is also supported by popular
development tools, such as ABEL and CUPL, via ICT
’
s
PEEL
Array fitters. A special smart translator utility adds
the capability to directly convert JEDEC files for other
devices into equivalent JEDEC files for pin-compatible
PEEL
Arrays.
Programming
PEEL
Arrays are EE-reprogrammable in all package
types, plastic-DIP, PLCC, SOIC and TSSOP. This makes
them an ideal development vehicle for the lab. EE-
reprogrammability is also useful for production, allowing
unexpected changes to be made quickly and without
waste. Programming of PEEL
Arrays is supported by
popular third party programmers.
Design Security and Signature Word
The PEEL
Arrays provide a special EEPROM security bit
that prevents unauthorized reading or copying of designs.
Once set, the programmed bits of the PEEL
Arrays
cannot be accessed until the entire chip has been
electrically
erased.
Another
signature word, allows a user-definable code to be
programmed into the PEEL
Array. The code can be read
back even after the security bit has been set. The signature
word can be used to identify the pattern programmed in the
device or to record the design revision.
