Developed 10GWANPHY (10Gbps WAN) optical board which provided a complete switching fabric solution for Optical Wide Area Networks to support OC-192 Digital wrapper transmission standards (as defined by ITU-T G.709). Developed architecture and coded Transport OverHead (TOH) FPGA which interfaced with HUDSON FEC (AMCC S19203), KHATANGA (AMCC S19205) devices and MPC8260 Motorola Power PC via its Local Bus. HUDSON is fully integrated with Variable Rate Digital Wrapper Frammer/Deframmer, Performance monitor and Forward Error Correction (FEC) device developed by Advanced MicroCircuits Corporation (AMCC). KHATANGA is a dense VLSI device developed by Advanced MicroCircuits Corporation (AMCC) that integrated a 10GbE MAC, a 64B/66B Physical Coding Sublayer (PCS) and a WAN Interface Sublayer (WIS) as baselined by IEEE P802.3ae task force. Used this FPGA to configure HUDSON through its microprocessor interface port, control and monitor status of Optical Channel Overhead bytes/Sonet Overhead bytes (Transport overhead and Section overhead of OC-192c frame) in data channels of HUDSON and to support all Insert/Drop Overhead Channels of HUDSON and KHATANGA.
Defined 16-bit Register Memory Map inside this FPGA with predefined memory locations for Parallel 8-bit Overhead Insert/Drop channels of HUDSON (both Encoder and Decoder sides) and for serial Insert/drop Channels of Hudson and KHATANGA. MPC8260 wrote overhead byte information into FPGA memory locations defined for those particular interfaces, which will later be inserted into insert channels on the next frame. On Drop channels FPGA collected Overhead byte information and stored them in internal predefined memory locations that will be later read by MPC8260. FPGA also monitored all status pins of HUDSON device like Loss of Clock, Out of Frame, Bit Parity Errors (BIP) and reported them to MPC8260. Implemented FPGA on Xilinx Virtex XCV200E series (FG456 package) and implemented all dual port RAMs using 28 Block RAMs available inside this FPGA. Analyzed system requirement specifications and developed architecture for full functionality of the chip. Automated critical parts of design verification using VERA HVL.

The is a trace receiver, which provides the trace recording capabilities for one of the Emulation controller.
The key features of the trace system ASIC are:
- Provides a maximum of 4 channels operated at single edge clocking (positive edge, negative edge, positive edge and negative edge, or alternatively 2 channels operated with Bi-phase clocking scheme.
- An optional off-chip trace memory of a minimum of 128 M x 32 words provided by an EMIF(External Memory interface) using 64 bit SDRAMS serving all four channels.
- On-chip trace static RAM memory organized as 32k x 64 (ie.256 bytes) serving all four channels. This memory is used as channel temporary buffers and scratch memory when SDRAM is used to store channel data.
- trace packet width from 1 to 20 bits
- 167 MHz processing rate
The trace peripheral has two distinct sections ,a “front end” and a “back end”. The front end (TPFE)acquires the trace data presented by the target and packs this data efficiently into 64-bit words. The Trace peripheral back end (TPBE) dispositions this data to trace memory, managing buffer locations, lengths, and host access to these buffers independent of whether the storing process is active. In short, the TPFE contains the acquisition, packing and buffering functions while the TPBE distributes the TPFE generated data into Trace buffers.

Hardware Design Engineer
Name of Project : PCI based high speed data acquisition card for signal Processing
- Designed the Hardware .
- Designed the FPGA& CPLD .
- Done the functional simulation & synthesis.
- Done extensive timing simulation with back annotating the sdf.
- Done schematic Entry using Mentor Graphics Tool.
PCI Add on card with PLX 9080 as PCI Bridge and on the local side uses one FPGA , which does all logic including bus arbitration and data transfer to FIFO . It actually acts as a local processor to PLX 9080. The input to the card includes 16-bit parallel data stream with strobe and 100 Mbps serial streams. Only one of these may be activated at a given time.
The design goal is to accept data rate upto 40MB/s, but the testing will be limited to 20 MB/s transfer to memory.
FPGA we were using was Spartan series XCS 40-4 ns. VHDL entry, compilation and functional simulation is done through Model SIM a front-end tool, then after this we had done synthesis through Leonardo spectrum. From that some edf(edif) files are generated and we open those files in the Xilinx tool. We are using Xilinx tool as the back end. Here we place and route the design and generate timing simulation data. From there one sdf(standard delay format) file is generated. This includes all the internal delays of the device. The Xilinx tool also generates a test bench file. We will apply our stimulus to that Test bench and we make that as the test bench for timing simulation. So when timing simulation comes we load our design file and the sdf file and simulate.
Usually the FPGA has to be configured using a serial EPROM. But in our case since the FPGA is being configured from the system side, it cannot be a permanent data as from EPROM. So we are using the CPLD to configure the FPGA. It will take data through the local bus and load it to the FPGA.
