+.SH NAME
+lvx \- Logical Versus eXtracted net-list comparator 
+.SH SYNOPSIS
+.TP
+\fBlvx \fIformat1 format2 filename1 filename2 \fB[ -a ] [ -o ] [ -f ]\fR
+.br
+.so man1/alc_origin.1
+.SH DESCRIPTION
+.B lvx
+compares two gate-level or block level net-list. The goal is to compare
+a specification net-list (logical net-list), the input to a place and route tool,
+with the physical net-list (extracted net-list) obtained by the
+.BR lynx (1)
+extractor.
+.br
+The net-list 1 is considered as the logical net-list and net-list 2 as the
+extracted net-list.
+.br
+.br
+.B lvx
+is an one-level hierarchical tool:
+.IP
+The two net-list are flattened, if the \fB-f\fP option is present, to the cells
+contained in the catalog file. The path to the catalog file is indicated in the
+.BR MBK_CATA_LIB (1)
+variable for the cell library, and in the
+.BR MBK_WORK_LIB (1)
+variable with the name
+.BR MBK_CATAL_NAME (1)
+for user blocks (
+.BR catal (5)
+) that are not to be flattened.
+.IP
+For both net-list, the instances are considered as black-boxes.
+.IP
+The two net-list must have the same external connectors names.
+.IP
+The two net-list must have the same instances names.
+.IP
+The two net-list must have the same signals names for unconnected signals.
+.IP
+The two net-list cannot directly contain transistors.
+.LP
+Comparison is performed in three steps:
+.IP
+Compare terminals.
+.IP
+Compare instances.
+.IP
+Compare connections.
+.IP
+Compare unconnected signals.
+.LP
+If an error occurs during first or second step, a message is
+immediately displayed and the third step will not start:
+.B lvx
+cannot compare connections (signals) if terminals
+or instances are not equivalent.
+.br
+The
+.B -o
+option allows to order connectors if the steps described before have been
+reached successfully.
+.I Extracted_netlist
+is then saved on disk. The file get the name
+.I filename2
+suffixed by the value of
+.BR MBK_OUT_LO (1)
+variable.
+.br
+Routers add automatically empty feed-through cells.
+These cells must not be taken into account in the comparison.
+A cell that have the
+.I F
+attribute in the catalog file (
+.B catal (5)
+) is considered as feed-through cell, and are deleted, in memory, from the
+net-list where it appears.
+.SH OPTIONS
+.TP
+.B "-a"
+Some routers generate layout with several physical connectors for power and
+ground (
+.I VDD
+or
+.I VSS
+).
+If those connectors are not internally connected, they will have different
+indexed names (
+.I VDD1
+,
+.I VDD2
+etc...) in the extracted net-list.
+It is possible to perform reduction on those power and ground connectors before
+comparison, using the -a option.
+After reduction, each instance contains only one
+.I VDD
+connector and one
+.I VSS
+connector, as the main figure.
+.TP
+.B "-o"
+In this case,
+.B lvx
+produces a modified net-list (saved with the name
+.I filename2
+), which is a copy of net-list 2 with ordered connectors.
+Terminals and instance connectors are relisted in the order of the models
+in net-list 1. The saved net-list is done with the
+.BR MBK_OUT_LO (1)
+format, so user has to set this variable before running
+.B lvx
+\&.
+If he does not, default value is used, and net-list 1 could be lost if
+filename are identical and input format same as output format.
+.br
+If -a option is used, then the saved net-list is the reduced net-list with only
+one
+.I VDD
+and one
+.I VSS
+\&.
+.TP
+.B "-f"
+The two net-lists are flattened to the leaf cells contained in the catalog
+file. Usually the extracted net-list is a flatten net-list, while the logical
+one can be a hierarchical net-list.
+.SH EXAMPLES
+With
+.I logical_netlist
+named amd2901.vst and the corresponding
+.I extracted_netlist
+as amd2901.al containing multiple power connectors, the command line is :
+.br
+.IP
+.B lvx
+vst al amd2901 amd2901 -a
+.br
+.LP
+.SH OUTPUT FILES
+.TP 20
+\fIfilename2\fP.\f4xx\fP
+Netlist view saved when the \fB-o\fP option is present. The suffixe depend on
+the \f4MBK_OUT_LO\fP(1) environment variable.
+.SH ENVIRONMENT VARIABLES
+.TP 20
+\f4MBK_CATA_LIB\fR
+contains the directories where the cell librtaries are.
+\f4MBK_WORK_LIB\fR
+contains the directory path of the working directory, usually set to
+\f4.\fR (dot).
+.TP
+\f4MBK_OUT_LO\fR
+contains the expected format of the netlist output.
+.TP
+\f4MBK_CATAL_NAME\fR
+contains the name of the user cell catalog.
+.SH SEE ALSO
+.BR lynx (1),
+.BR MBK_OUT_LO (1),
+.BR MBK_WORK_LIB (1),
+.BR MBK_CATA_LIB (1),
+.BR MBK_CATAL_NAME (1),
+.BR catal (5)
+\&.
+.SH DIAGNOSTICS
+The string "_logic" is appended to the net-list 1 and the string "_extract", is
+appended to the net-list 2.
+.LP
+Two kinds of error message can occur:
+.IP
+A fatal error causes the program to exit.
+It happens when one of the net-lists is not correct,
+.B lvx
+cannot construct internal structure for compare.
+.IP
+A compare error occurs when the figures are not identical.
+It happens when basic objects (instances, connectors) do not exist in both
+net-list, or when connections (signals) do not connect same terminals or
+instances in the two net-lists.
+.LP
+Exit code 0 is returned for identical net-lists.
