NAME
     icncsim - ICPRO tool wrapper for Cadence NCSIM simulations

SYNOPSIS
     icncsim [-OPTION] <target>

      -OPTION     : -h | -help | -d | -debug | -noxov | -nosvn | -nocommit
                    -unit=<unit> | -tc=<testcase> | -flow=<FLOW>
      <target>    : prepare | makefile | runGUI | runBatch

     is used to prepare, initialize and run Cadence NCSIM
     simulation environment.

DESCRIPTION
     Prepare, initialize and run Cadence NCSIM simulation
     environment for a ICPRO design unit.

     First run icncsim prepare target to prepare simulation
     directory structure ("simulation/ncsim/testcase_name") and
     required files. The testcase name could be defined by using
     the -tc=NAME switch. If no name is given, a default name
     will be generated. If the project is under revision control,
     directories and files are added and initially commited to
     repository. The revision control functionality could be
     disabled completely by using the -nosvn switch.
     Alternatively the initial commit can be suppressed using the
     -nocommit switch.  For the excecution of prepare target your
     current working directory has to be a unit directory or you
     have to define the unit for which the testcase should be
     prepared by using the -unit=NAME switch. For all other
     targets your CWD has to be a testcase directory or you have
     to define the unit name (if you are not in a specific unit
     directory) and the testcase name (-tc=NAME).

     Next step icncsim makefile parses dependencies of this unit
     and adds dependencies to newly created "Makefile.ncsim". A
     file "Makefile.var" (under revision control) will be
     included by <Makefile.ncsim> and should contain users
     modifications (e.g. additional tool switches). So
     "Makefile.ncsim" should be checked in only, if modifications
     cannot be done in included <Makefile.var>.

     Prior to run simulation user has to modify or adapt testcase
     patterns (initial "testcase.v") and TCL-run control and
     coverage analysis scripts in "./scripts" if needed.  icncsim
     runGUI or icncsim runBatch starts simulation, either in GUI
     or in batch mode (the latter usually for automated runs,
     e.g. regressions).

OPTIONS
     -h|-help
             show extended manpage information

     -d|-debug
             show extended debugging information

     -tc=<testcase_name>
             Prepares an additional simulation testcase directory
             "simulation/ncsim/<testcase_name">.

     -flow=<FLOW>
             Selects flow template for prepare target.

     -noxov|-noxmloverwrite
             This switch prevents icncsim from overwriting xml
             report message database (report_messages.log.xml).
             (normally used in regression scripts to collect
             messages for simulation and postprocessing, e.g.
             coverage)

     -nosvn  Completely disables SVN functionality during prepare
             target.

     -nocommit
             Suppresses initial template commit during prepare
             target.

TARGETS
     prepare generates and initializes NCSIM directory structure

     makefile
             generates NCSIM makefile, parses dependencies

     runGUI  run NCSIM Simulation in GUI mode;

     runBatch
             run NCSIM Simulation in batch mode;

EXAMPLES
     Prepare and start simulation within design unit "adder":

         % icncsim prepare
         % cd simulation/ncsim/adder_tc0

         adapt <testcase.v> and TCL-scripts

         % icncsim makefile
         % icncsim runGUI

INTERNAL USE
     icncsim [-report=<FILE> -reportverbose] cov_post

     Used to postprocess iccr coverage reports <FILE> and
     calculates summary coverage percentage.  Filename
     <./coverage_report.tab> is default for <FILE>. If
