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 sen-
       sitive, 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.
