Libero Configurators

Libero is a EDA tool to create electronic design.It used for creation of complex FPGA based design. It will simulate,synthesis,place and route FPGA based design.

Worked on below RTG4, PolarFire FPGA Configurators.

Roles and Responsibility:

• Worked on Actgeno RAM netlist generation module, Worked on RAM Configurators
• Worked on DDR, DDR3, DDR4, LPDDR3, LPDDR4 Configurators, DDRPHY and IO Configurators
• Worked on Ram initialization module (UIC project)
• Worked on Memory Map Generator tool
• Worked on Device and Memory Initialization tool
• Worked on SNVM, uPROM Configurator
• Worked on System Services Configurator
• Worked on CCC Configurator
• Worked on CCC (Clock conditioning circuitry), PLL (SSM Support), DLL, TxPLL
• Worked on MSS Configurator
• Worked on Design Creation using various FPGA tools (Quartus, Vivado, Libero)
• Worked on BfmToVec Compiler

FSBL

Fsbl is first stage boot loader on zynq based SOC of Xilinx. Before running any application on board it will boot first. It has 4 stages described as below.

1. Initialization: It will initialize processor, peripheral like i2c, mio, ddr, system drivers.

2. Boot device initialization and Header Validation: It will initialize primary boot device

Like qspi, nand, SD etc. and validate the header.

3. Partition copy, Validation: It will perform Partition header validation, Partition

Copy, Partition Validation.

4. Handoff: It will perform Post Configuration and Handoff to CPU’s.

Roles and Responsibility:

• Working on PR related to FSBL, Ex
• Early handoff, Wrapper for psu_init, X1, X2 bus width support for Qspi
• Working on CR related to FSBL, Ex
• R5 Fsbl vector overwritten by R5 Application, Secure boot of Fsbl failing due to big endian code activation in bsp
• Worked on MISRA-C Compliant for FSBL
• Customized bsp according to FSBL usages
• Worked on QSPI, NAND, Linux device driver
• Testing fsbl performance on various boards like zcu102, zc1751

PMU FIRMWARE

PMU FIRMWARE is a platform management unit firmware for Xilinx SOC ,which will run on microblaze cpu through PMU RAM,It will handle and control the interrupt between all the processors present in zynq and zynqmp SOC,It will use IPIPSU driver for this purpose.

Roles and Responsibility

● Working on PR related to PMUFW.

● Working on CR related to PMUFW.

● Created the versionless automated building of PMUFW through git ,Without using any tools.

Ubpf Vm

Ubpf is open source project.This project is aims to create an Apache licensed Library for executing eBPF programs.The primary implementation of eBPF lives in linux kernel.We used this open source project to load bpf plugins in microblaze based board.

Roles and Responsibility:

● Cloned the source code from Gibhub and started working on it to create customized plugin loader for microblaze.

● Resolved .text, .data, .rel.text, .rodata.str1 section.

● Implemented stack for multiple function calls.

● Increased performance, Reduce the size of code.

● Released successfully this new customized BPF based VM.

1VU,Uniserve

TRAI regulations mandate that a subscriber should not have more than a stipulated number of connections within a specific telecom circle. Customer information on the other hand is captured by multiple systems operating in silos and manual data entry resulting in possible inconsistencies in information. Online and offline De-duplication of records to establish customer identity has the following challenges: Missing, conflicting, corrupted information and data entry errors to match customer information Ever growing customer subscriptions complicating the de-duplication process Businesses need to check with lists of blacklisted customers and National Do Not Call (NDNC) prior to onboarding , Parameters like name, addresses etc being captured differently at each customer interaction, 1VU tool does above features.

Diagnostic code for 8051 Development Board.

● In this project developed the testing code for devices like led, switches, uart, lcd, 7-seg display,i2c,spi,dc motor, keypad.

Preprocessor using C language for GCC compiler.

● Implemented some features of preprocessor like macro replacement, header file inclusion, comment removal using C language programming.
