I'm getting the following error while while using the command abc -liberty cmos_cells.lib (logical mapping). I was able to techmap, fsm map and memory map the veriog code. dfflibmap gets executed without any problem.

It seams to me that ABC can't correctly parse the auto-generated read_lib command because of the spaces in F:/FINAL YEAR POJECT/.., try to specify the path to the cell library as absolute path, starting with F:/FINALY~1/ instead of F:/FINAL YEAR POJECT/.., or simply rename that directory so it does not contain any whitespace in its name (or move Yosys to some other place).

I'm currently looking for a way to execute iverilog in in Yosys, to be more exact at the write_verilog step.
I need to feed iverilog the file, which will be generated by write_verilog (reason is, I need to uphold the variable source information, which are kept in the yosys attributes).
However the execute() function only writes into the file upon function end.
If I were to call iverlog testbench.v design.v with design.v being the file which is generated through write_verilog, I get an error, telling me it's missing modules.
Is it possible to carry out commands, that depend on the file which is generated after execute() has run through, while still being in the verilog backend?
You could use a script instead, to run iverilog after write_verilog, inside a Yosys script a line beginning ! is passed to the shell:
write_verilog design.v
!iverilog testbench.v design.v
I am working with a CMake (version 2.8.12) script (CMakeLists.txt) that worked on a previous computer (and probably still does). The problem seems to be that my username on my newer computer now contains a #. The CMake script now fails with this report:
"add_custom_command called with OUTPUT containing a '#'. This character is not allowed."
The parameter ${CMAKE_CURRENT_BINARY_DIR} contained in this line:
add_custom_command(OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/DBSTYPEDEFS.F77 COMMAND ${MKDBSTYPEDEFS_EXE} DEPENDS {MKDBSTYPEDEFS_EXE})
expands out to include my user-name as part of the full pathname.
Q: Is there a way to solve this problem?
If you cannot simply change your username on the machine, try moving the repository to another location on the machine.
If you current have the repository repo1 in your home directory, you'll get an expansion to something like this:
add_custom_command(OUTPUT /home/don#robinson/repo1/generated_files/DBSTYPEDEFS.F77 COMMAND ${MKDBSTYPEDEFS_EXE} DEPENDS {MKDBSTYPEDEFS_EXE})
which was causing your error. Moving the code to somewhere else, say /usr/local/repo1, the expansion in add_custom_command now looks like this:
add_custom_command(OUTPUT /usr/local/repo1/generated_files/DBSTYPEDEFS.F77 COMMAND ${MKDBSTYPEDEFS_EXE} DEPENDS {MKDBSTYPEDEFS_EXE})
which should remove the error.
Your script likely will fail when ran on any directory whose full path contains the hash symbol. Similarly, for the less-than and greater-than sign.
Since your username contains the hash symbol, you either have to change your username or to move the directory to a location whose path does not contain the hash symbol. See https://cmake.org/cmake/help/latest/policy/CMP0053.html for other disallowed characters. This is CMP0053.
If you want to keep your hashtagged username, the process will be more complicated, but it is something in the lines of
set(varname "otherwise & disallowed $ characters")
message("${${varname}}")
I have a model of a heating process on Ansys Multiphysics, V11.
After running the simulation, I have a script to plot a temperature profile:
!---------------- POST PROCESSING -----------------------
/post1 ! tdatabase postprocessor
!---define profile temperature
path,s_temp1,2,,100 ! define a path
ppath,1,,dop/2,0,0 ! create a path point
ppath,2,,dop/2,1.5,0 ! create a path point
PDEF,surf_t1,TEMP, ,noav ! print a path
plpath,surf_t1 ! plot a path
What I now need, is to save the resulting path in a text file. I have already looked online for a solution, and found the following code to do it, which I appended after the lines above:
/OUTPUT,filename,extension
PRPATH,surf_t1
/OUTPUT
Ansys generates the file filename.extension but it is empty. I tried to place the OUTPUT command in a few locations in the script, but without any success.
I suspect I need to define something else, but I have no idea where to look, as Ansys documentation online is terribly chaotic, and all internet pages I've opened before writing this question are not better.
A final note: Ansys V11 is an old version of the software, but I don't want to upgrade it and fit the old model to the new software.
For the output of the simulation (which includes all calculation steps, and sub-steps description and node-by-node results) the output must be declared in the beginning of the code, and not in the postprocessing phase.
Declaring
/OUTPUT,filename,extension
in the preamble of the main script makes such that the output is stored in the right location, with the desired extension. At the end of the scripts, you must then declare
/OUTPUT
to reset the output file location for ANSYS.
The output to the PATH call made in the postprocessing script is however not printed in the file.
It is convenient to use
*CFOPEN,file,ext
*VWRITE,Vector(1,1).Vector(1,2)
(2F12.6)
*CFCLOSE
where Vector(1,1) is a two column array created by *DIM, and stores your data to output to file
As this is a special command, run it from file i.e. macro_output.mac
When developing Pig scripts that use the STORE command I have to delete the output directory for every run or the script stops and offers:
2012-06-19 19:22:49,680 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 6000: Output Location Validation Failed for: 'hdfs://[server]/user/[user]/foo/bar More info to follow:
Output directory hdfs://[server]/user/[user]/foo/bar already exists
So I'm searching for an in-Pig solution to automatically remove the directory, also one that doesn't choke if the directory is non-existent at call time.
In the Pig Latin Reference I found the shell command invoker fs. Unfortunately the Pig script breaks whenever anything produces an error. So I can't use
fs -rmr foo/bar
(i. e. remove recursively) since it breaks if the directory doesn't exist. For a moment I thought I may use
fs -test -e foo/bar
which is a test and shouldn't break or so I thought. However, Pig again interpretes test's return code on a non-existing directory as a failure code and breaks.
There is a JIRA ticket for the Pig project addressing my problem and suggesting an optional parameter OVERWRITE or FORCE_WRITE for the STORE command. Anyway, I'm using Pig 0.8.1 out of necessity and there is no such parameter.
At last I found a solution on grokbase. Since finding the solution took too long I will reproduce it here and add to it.
Suppose you want to store your output using the statement
STORE Relation INTO 'foo/bar';
Then, in order to delete the directory, you can call at the start of the script
rmf foo/bar
No ";" or quotations required since it is a shell command.
I cannot reproduce it now but at some point in time I got an error message (something about missing files) where I can only assume that rmf interfered with map/reduce. So I recommend putting the call before any relation declaration. After SETs, REGISTERs and defaults should be fine.
Example:
SET mapred.fairscheduler.pool 'inhouse';
REGISTER /usr/lib/pig/contrib/piggybank/java/piggybank.jar;
%default name 'foobar'
rmf foo/bar
Rel = LOAD 'something.tsv';
STORE Rel INTO 'foo/bar';
Once you use the fs command, there a lot of ways to do this. For an individual file, I wound up adding this to the beginning of my scripts:
-- Delete file (won't work for output, which will be a directory
-- but will work for a file that gets copied or moved during the
-- the script.)
fs -touchz top_100
rm top_100
For a directory
-- Delete dir
fs -rm -r out
I'm working on a script that processes a folder and there is always one file in it I need to rename. The new name should be the parent directory name. How do I get this in a batch file? The full path to the dir is known.
It is not very clear how the script is supposed to become acquainted with the path in question, but the following example should at least give you an idea of how to proceed:
FOR %%D IN ("%CD%") DO SET "DirName=%%~nxD"
ECHO %DirName%
This script gets the path from the CD variable and extracts the name only from it to DirName.
You can use basename command:
FULLPATH=/the/full/path/is/known
JUSTTHENAME=$(basename "$FULLPATH")
You can use built-in bash tricks:
FULLPATH=/the/full/path/is/known
JUSTTHENAME=${FULLPATH##*/}
Explanations:
first # means 'remove the pattern from the begining'
second # means 'remove the longer possible pattern'
*/ is the pattern
Using built-in bash avoid to call an external command (i.e. basename) therefore this optimises you script. However the script is less portable.
