BOOM - BOOlean Minimization
boom [-VTOAP] [-l num] [-d num] [-i num] [-a num] [-sjbgpwtmorn]
BOOM is used for the first step of the synthesis process. It optimizes
a behavioural description using a Reduced Ordered Binary Decision
Diagram representation of logic functions. The file filename is the
input behavioural description and must be written in vbe(5) format.
The resulting behavioural optimized description is saved with the name
outname or input_name_o in vbe(5) format.
indicates the path to the read/write directory for the
-V Verbose mode on. Each step of the optimization is displayed
on the standard output.
-T Trace mode on. Some debug informations are displayed on the
-O Reverses initial Bdd variables order.
-A BOOM performs a local optimization and keeps the architecture
of the initial description by saving most of the intermediate
signals. This mode is well-suited for big or regular
circuits such as multipliers, adders. By default BOOM
performs a global optimization and removes most of the
intermediate signals so that the outputs are expressed in
terms of the inputs or the internal registers. This mode is
well-suited for random circuits such as FSMs.
-P Uses a parameter file input_name.boom describing optimization
directives and constraints. (see below for the exact syntax)
# Example of .boom file
# The list of auxiliary signals that have to be kept
# during optimization.
# Generally carry signals, ram address signals etc ...
# The list of auxiliary signals which assigned
# expression won't be modified.
# Generally it's ram output signals.
-l num Specifies the optimization level [0-3] (default is 0, low
-d num Specifies the delay optimization percent (default is 0%
delay, 100% surface).
-i num Specifies the number of iterations for the choosen
optimization algorithm (for experts only).
-a num Specifies the amplitude during bdd reordering (for experts
Specifies which algorithm has to be used for the boolean
boom(5), vbe(5), asimut(1), boog(1), MBK_WORK_LIB(1).
