NAME
genlib - Procedural design language based upon C.
DESCRIPTION
genlib is a set of C functions dedicated to procedural generation
purposes. From a user point of view, genlib is a circuit's description
language that allows standard C programming flow control, variable use,
and specialized functions in order to handle vlsi objects.
Based upon the Alliance mbk data structures, the genlib language gives
the user the ability to describe both netlist and layout views,
thus allowing both standard cell and full custom approachs.
NETLIST CAPTURE
It is a hierachical structural description of a circuit in terms of
connectors (I/Os), signals (nets), and instances.
The function calls used to handle the netlist view are :
o GENLIB_DEF_LOFIG(3)
o GENLIB_SAVE_LOFIG(3)
o GENLIB_LOINS(3)
o GENLIB_LOCON(3)
o GENLIB_LOSIG(3)
o GENLIB_FLATTEN_LOFIG(3) Some facilities, in order to create vectors
are also available :
o GENLIB_BUS(3)
o GENLIB_ELM(3)
STANDARD CELL PLACEMENT
The following functions allows to define a placement file for a
standard cell design. This file can be used by the standard cell router
ocr(1) :
o GENLIB_DEF_PHSC(3)
o GENLIB_SAVE_PHSC(3)
o GENLIB_SC_PLACE(3)
o GENLIB_SC_RIGHT(3)
o GENLIB_SC_TOP(3)
o GENLIB_SC_LEFT(3)
o GENLIB_SC_BOTTOM(3)
FULL CUSTOM SYMBOLIC LAYOUT
Those functions are dedicated to optimized full custom procedural
layout. In order to provide some process independance, Alliance uses a
symbolic layout approach (fixed grid without compaction).
The symbolic objects are segments (wires), vias (contacts), connectors
(I/Os), references and instances. For more informations, see phseg(1),
phvia(1), phcon(1), phref(1), phins(1) and alc(1).
o GENLIB_DEF_PHFIG(3)
o GENLIB_SAVE_PHFIG(3)
o GENLIB_DEF_AB(3)
o GENLIB_DEF_PHINS(3)
o GENLIB_PHCON(3)
o GENLIB_COPY_UP_CON(3)
o GENLIB_COPY_UP_CON_FACE(3)
o GENLIB_COPY_UP_ALL_CON(3)
o GENLIB_PHSEG(3)
o GENLIB_COPY_UP_SEG(3)
o GENLIB_THRU_H(3)
o GENLIB_THRU_V(3)
o GENLIB_THRU_CON_H(3)
o GENLIB_THRU_CON_V(3)
o GENLIB_WIRE1(3)
o GENLIB_WIRE2(3)
o GENLIB_WIRE3(3)
o GENLIB_PHVIA(3)
o GENLIB_PLACE(3)
o GENLIB_PLACE_RIGHT(3)
o GENLIB_PLACE_TOP(3)
o GENLIB_PLACE_LEFT(3)
o GENLIB_PLACE_BOTTOM(3)
o GENLIB_PLACE_ON(3)
o GENLIB_PHREF(3)
o GENLIB_COPY_UP_REF(3)
o GENLIB_COPY_UP_ALL_REF(3)
o GENLIB_PLACE_VIA_REF(3)
o GENLIB_PLACE_CON_REF(3)
o GENLIB_PLACE_SEG_REF(3)
o GENLIB_FLATTEN_PHFIG(3)
o GENLIB_GET_REF_X(3)
o GENLIB_GET_REF_Y(3)
o GENLIB_GET_CON_X(3)
o GENLIB_GET_CON_Y(3)
o GENLIB_HEIGHT(3)
o GENLIB_WIDTH(3) In order to have information about each of these
functions, use the online documentation with man(1), as in man
function-name.
It is strongly recommended to read some books on C programming, in
order to take full advantage of the C flow control possibilities, as it
may greatly reduce the size of a genlib source code.
ENVIRONMENT VARIABLES
o MBK_IN_LO(1), default value : al
o MBK_OUT_LO(1), default value : al
o MBK_IN_PH(1), default value : ap
o MBK_OUT_LO(1), default value : ap
o MBK_CATA_LIB(1), default value : .
o MBK_WORK_LIB(1), default value : .
o MBK_CATAL_NAME(1), default value : CATAL See the corresponding manual
pages for further informations.
In order to compile and execute a genlib file, one has to call genlib
with one argument, that is the genlib source file. The source file
must have a .c extension, but the extension should not be mentionned on
the command line.
The names used in genlib, as arguments to genlib functions, should be
alphanumerical, including the underscore. They also are not case
sensitive, so VDD is equivalent to vdd. Vectorized connectors or signal
can be declareds using the [n:m] construct.
SYNOPSIS
genlib [ -cklmnv
] [ --no-rm-core ] [ --keep-makefile ] [ --keep-exec ] [ --keep-log ]
[ --no-exec ] [ --verbose ] program [ -e program_args ]
OPTIONS
o <program> : the name of the C file containing the genlib program,
whitout extention. Mandatory argument.
o [--no-rm-core|-c] : in case of core dump, do not remove the generated
core file. This option must be used with [--keep-exec|-k].
o [--keep-makefile|-m] : do not erase the generated makefile after
execution.
o [--keep-exec|-k] : keep the generated executable after the genlib
run.
o [--keep-log|-l] : do not erase the log file after a successfull
completion (the log is keeped after a faulty run).
o [--no-exec|-n] : do not run the generated program. Should be used
with [--keep-exec|-k].
o [--no-verbose|-v] : self explanatory.
o [-e] : all the following arguments are handled to the compiled
program.
EXAMPLES
Compile and run a file amd2901.c :
genlib -v amd2901

DIAGNOSTIC
Many errors may occur while executing the source file, so refer to the
proper genlib function manual for more. When an error occur, genlib
left a log file <program>.grr. As <program>.c is a C program, all
syntatic C error can occurs...
All genlib functions are listed below alphabetically sorted.
