+.SH DESCRIPTION
+\fBocp\fP is an automatic place tool for standard-cells.
+.br
+
+\fBinput net-list\fP
+.br
+The \fInetlist\fP file describes the input net-list.
+.br
+\fBocp\fP supports a hierarchical net-list. In this case the net-list is flattened by the placer according to the catalog file. The net-list format can be : structural VHDL, EDIF, or ALLIANCE internal format according to the environment variable \fBMBK_IN_LO\fP.
+.br
+
+\fBoutput layout\fP
+.br
+The file containing the routed block will have the name \fIfilename\fP. The output format is defined by the environment variable \fBMBK_OUT_PH\fP.
+.br
+
+.SH OPTIONS
+.br
+\fBOptional cells placement file\fP
+.br
+\fB-partial <NAME>\fP
+.br
+A user defined placement can be specified, thanks to a placement file.
+.br
+The optional placement file must be given by the user. It must have an extension that denotes the format defined by the environment variable \fBMBK_IN_PH\fP.

+\fBMargin\fP
+.br
+It is possible to force the free area of the physical view.
+.br
+The \fB-margin <MARGIN>\fP option allow to set The amount of free area added in percentage of the cells area.
+.br
+The resulting area will be equal to CELL_AREA * (1 + <MARGIN>).
+.br
+By default, the margin value is 0.2 (20%)
+.br
+
+\fBNumber of rows\fP
+.br
+\fB-rows <NR>\fP option forces the design to be placed in <NR> rows.
