Some Significant Projects:

Project

TRW

Customer

TRW US

Description

Globally located Engineers requirement will be assigned to layout Engineer in the form of Service request. More than 50 board are designed for automotives. These are into air bag sensors, steering, power break etc..

Below steps are followed for each service request

Periodic review’s with design engineer for schematics and layout.

Project

POWC

Customer

Ericsson, Sweden

Description

This Project aims at replacement of ASIC with FPGA on the POWC board which is used in GSM base station/core network controller. The design of the board involves replacement of ASIC with FPGA and associated changes. Also the board should be RoHS compliant. The board is designed to reproduce the existing functionality with new set of components. Schematic and Layout designs are to be implemented. The board is verified for functionality at board level and system level. The board is subjected to different stress tests to ensure reliability. Board is verified in two stages (two prototypes) before launch for production.

Tools

Cadence Allegro16.2 PCB. GC-PREVUE for Gerber view.

Project

IPNAX

Customer

Ericsson, Sweden

Description

The purpose of the IPNAX Project is to deliver the functionality required to connect system test plant APZ 212 3x/40and server (APG40) to the Inter-Platform Network (IPN). This provides a fast connection between the Central Processor (CP) and the Adjunct Processor (AP), and allows the CP to interwork with other processing platforms. The FPGA on PBA provides an interface to the APZ 212 RPHB on one side and the Peripheral Component Interconnect (PCI) bus on the Other side.
