************** FIT1500.M - Fitting Options Atmel ATF1500 **************
In most designs, you do not need to use any of the Fitting Options. If
your design is very complex and require some "tweaking" to get higher
logic utilization or performance, then the ATF1500 fitter options may
be used.
How to use the ATF1500 Fitting Options:
--------------------------------------
1. Copy the FIT1500.M file to your project directory. This file has
the CUPL macros for implementing the fitter options.
2. To use the ATF1500 Fitter Options, you must insert the following
statement in your CUPL file.
$INCLUDE FIT1500.M
The above statement must be specified ahead of the fitting option(s).
E.g.
.
.
$INCLUDE FIT1500.M
GLOBAL(Reset); "Force the Reset pin to the global reset pin
.
.
3. When using the CUPL macros, you can only pass a single parameter to
each macro. For instance, if you need to declare X0, X1, X2 to be
expander nodes, you cannot do the following:
EXP(X0, X1, X2);
Instead,you must specify in the following manner:
EXP(X0);
EXP(X1);
EXP(X2);
Special Note
------------
If you specify the following macros in your CUPL file:
EXP (X0); "EXP option has higher priority than EXP_ALL
EXP_ALL (OFF); "(even when EXP_ALL is OFF).
.
.
The above is true for all macros that have the global ON/OFF and
individual signal setting options. The individual setting option
always has a higher priority than the global setting option.
Higher Priority Lower Priority
