Synthesizing individual blocks separately
It would be required to synthesize individual blocks in SPARC separately. For example, the method to synthesize the Load Store Unit is described here.
You
need to have successfully run rsyn -how?
example
lsu unit present in design/sys/iop/sparc/lsu
Steps
1.
Create a work folder anywhere you like
2.
cd into design/sys/iop/sparc/lsu
3.
Use the following script to collect the flat_files from the location
4.
Use the following script to extract the flat nestlist from all
modules inside lsu to a folder called flat_files
Script:
file_collect.sh (location /design/sys/iop/sparc/lsu)
cd
/home/ar2654/opt/OpenSPARCT1/design/sys/iop/sparc/lsu
for
FILE in $(find . -type f | grep -e "flat")
do
echo "cp ${FILE}
/home/ar2654/opt/OpenSPARCT1/design/sys/iop/sparc/lsu/flat_files"
cp ${FILE}
/home/ar2654/opt/OpenSPARCT1/design/sys/iop/sparc/lsu/flat_files
done
5.
copy the files that are present in the flat_files folder to the work
folder.
6.
Copy the top file for the lsu namely lsu.v present in
design/sys/iop/sparc/lsu/rtl to the work folder
6.
Invoke design vision, run the configuration script to set up
the libraries and work folders etc
7.
File -> analyze, add all the files that are present in the work
directory
8.
File -> Elaborate, you will get warnings saying that sram modules
(bw_r*) are missing, they cannot be synthesized because they are
memory modules
9.
Design -> compile
10.
Command "report_qor > result_file" to report the area
gate information etc.
11.
Save the synthesized file. File -> save
