Synopsys vhdlan: Common issues/solutions re-compiling the M1.3/M1.4 XSI simulation libraries

説明

Keywords: encrypted, IEEE, non-ascii, VSS, vhdlan, simulation, simprims, logiblox, ftgs

Urgency: Standard

General Description:

When M1.3/M1.4 XSI is installed, if the version of Synopsys is newer than v3.4b, the
M1.3/M1.4 XSI simulation libriaries must be re-compiled before using them. In the Synopsys
toolset, M1 simulation libraries must be recompiled with the current version of Synopsys in use.

(If the version of Synopsys used with M1.3/M1.4 is 3.4b, then the M1.3/M1.4 software just has
to be installed. No re-compilation of the XSI XDW and XSI simulation libaries is needed.)

During recompilation of the M1.3/M1.4 simulation libraries with a version of Synopsys newer than
v3.4b, the user may see the following messages:

Warning: Can't read link_library file 'your_library.db' (UID-3)

and/or:

Error detected in non-ASCII(possibly encrypted) file

and/or something similar to:

Error compiling file : ../../lib/simprims/X_XOR6__X_XOR6_V.c, Reverting to
Interpreted code for design unit : X_XOR6_V.
Warning: vhdlan,1500 /xilinx/vhdl/src/simprims/simprim_VITAL.vhd(6392):

ソリューション

1

If the only message you see, while running analyze.csh and/or any of the .dc scripts in
$XILINX/synopsys/libraries/sim/src, is:

Warning: Can't read link_library file 'your_library.db' (UID-3)

This warning is generally not of concern and generally the re-compilation of the libraries was successful.

2

While running the analyze.csh and/or any of the .dc scripts in $XILINX/synopsys/libraries/sim/src,
if the following error is seen:

Error detected in non-ASCII(possibly encrypted) file

The re-compilation of the simulation libraries has failed.


Please check all of the following:

Make sure that the $XILINX environment variable is set to the top of the M1.3 software tree.

Make sure that the $SYNOPSYS environment variable is set to the top of the Synopsys software tree.

Use only Synopsys v3.4b or later.

The user executing the analyze.csh or .dc scripts in $XILINX/synopsys/libraries/sim/src must have
write permissions for $XILINX/synopsys/libraries/sim/lib.

Delete the contents of the sub-directories in $XILINX/synopsys/libraries/sim/lib; delete the contents
of (including sub-directories) in:

$XILINX/synopsys/libraries/sim/lib/logiblox
$XILINX/synopsys/libraries/sim/lib/simprims
$XILINX/synopsys/libraries/sim/lib/xc3000a/ftgs
$XILINX/synopsys/libraries/sim/lib/xc4000e/ftgs
$XILINX/synopsys/libraries/sim/lib/xc5200/ftgs
$XILINX/synopsys/libraries/sim/lib/xc7000/ftgs
$XILINX/synopsys/libraries/sim/lib/xc9000/ftgs

After checking all of the above, attempt to re-run the analyze.csh, and/or .dc scripts in
$XILINX/synopsys/libraries/sim/src

While running the analyze.csh in
$XILINX/synopsys/libraries/sim/src/logiblox
or in
$XILINX/synopsys/libraries/sim/src/simprims, the
following message appears:


Error compiling file : ../../lib/simprims/X_XOR6__X_XOR6_V.c, Reverting to
Interpreted code for design unit : X_XOR6_V.
Warning: vhdlan,1500 /xilinx/vhdl/src/simprims/simprim_VITAL.vhd(6392):


The interpretive re-compilation of the M1.3 XSI logiblox/simprim libraries has succeeded, but
the C-compiler based re-compilation has failed.

This typically happens on Solaris platforms but not on SunOS 4.x. Solaris platforms do not come
with the cc C-compiler which is compatible with vhdlan -c. The cc C-compiler for Solaris must be
purchased from Sun. SunOS, on the other hand, does come with the cc C-compiler which is usually
compatible with vhdlan -c.

When this message happens, the user can opt to use the libraries that were created. If the user is
simulating a 'small' design, use of the C-compiled or interpretive based logiblox/simprim libraries will
probably not make a big difference in simulation time. On the other hand, if the user has a 'large'
design to simulate, it is highly recommended that the user get the vhdlan -c option to work.

Please check your Synopsys on-line docs (Iview), or contact Synopsys (http://www.synopsys.com)
for information on C-compilers compatible with vhdlan -c.

If you are using Synopsys 3.4b, or later, with Solaris than the C-compiler that should be used
with vhdlan -c should be v3.0.1 of the cc C-compiler with the Solaris OS.

What follows is an example of setting up the cc C-compiler v3.0.1 on the Solaris OS. Please
consult Synopsys for compatible C-compilers that can be used with vhdlan -c:

set path =(. /path/to/cc/compiler/bin $path)
setenv MANPATH /path/to/cc/compiler/docs/man:/usr/man:${MANPATH}
setenv LD_LIBRARY_PATH /path/to/cc/compiler/lib:${OPENWINHOME}/lib:${LD_LIBRARY_PATH}
setenv LM_LICENSE_FILE port@hostname


After making sure the above settings are correct, in the .synopsys_vss.setup file in the
$XILINX/synopsys/libraries/sim/src/logiblox and $XILINX/synopsys/libraries/sim/src/simprims
directories add the following line to the .synopsys_vss.setup file:
