Microsemi SOC – June 15 to Current
1. PORTING Automation
AIM: Reduce time and manual intervention required to convert ASIC RTL to on FPGA emutable
RTL.
Wrote PERL script that will enable user to download a new ASIC RTL available on svn and convert
it to FPGA usable RTL so that the whole team can further use the ported RTL and test it.
Earlier process used 1 complete day(or more), reduce to 1hr job with no human intervention.
Script made was modular and was divided in functions as-
a. Download ASIC RTL
b. Download already ported FPGA RTL
2. c. Compare in TOP file changes
d. Compare simulation file changes
e. Compare synthesis file changes
f. Edit Clocking instances
2. PROGRAMING Automation
AIM: To remove manual intervention to generate a programming file for Microsemi’s FPGA with
specific configurations.
Wrote PERL script which allows the user to generate a configuration file that is used by internal
Microsemi tool to generate a programming file. The PERL script requires particular set of inputs and
configurations.
Earlier process used 0.5 hour manually to generate 1 particular programming file while the process
was reduced to 30-40 seconds.
3. Emulation Use Models
AIM: To write use models to test various chip functionalities and security features.
Read the specifications provided by designers and formulated the use models and use cases and
gave review. Following Use Models were covered by me-
1. Low Power mode.
2. Only Fabric on mode.
3. Security features.
4. ARM based features.
5. Device initialization features.
Review of above tests still in process.
Vitesse Semiconductor – July 14 to May 15
1. Functional Validation Of 10G Physical Layer Chip
AIM: To validate following list of Features of 10G PHY:
• GPIO Functionality
• Loopbacks
• Stress Tests
• Clock Output Tests
• Squelch Tests
• Low Power Mode Tests
• BIST test
Test cases were written in Tcl and automated to require least human intervention.
2. Development/Automation of GPIB Library
AIM: To develop GPIB library to automate testing which requires CRO/analysers/Power switching.
Wrote Tcl scripts and created routines that will able to control GPIB available devices using our
environment and our commands. Done first time in Vitesse SC India lab, got appreciation from
IDC head.
3. Development of Unified Validation Environment
AIM: To create a new infrastructure for regressions similar to UVM for validation.
I worked to edit parser written in C and Tcl to generate register mapping file in tcl from XML file. I
wrote as well as edited functions for DUT read/write and tester initialization and fire up. I worked
to create and implement regression system for validation.
4. Board Design for Validation
I worked to design the validation characterization board in house rather than transporting from
other sites. I acted as lead of team of size 3 and worked on open source tool from fedora to
develop Arduino board. Layout is still in progress.
