High speed (sub-nano edges) signal integrity analysis of a 10 GHz network analyser card. This project was a PCB design with FPGA to DDR SDRAM interfaces with a PHY laser module up to 700 MHz using LVDS and SSTL signalling. We created and verified IBIS models for use in PCB environment simulations. SPICE analog simulations of reflections were used to evaluate the PCB track termination scheme effectiveness.

Design of a high speed (266 MHz+) SDRAM padlogic interface for the core logic of an embedded microprocessor. This project required analysis of the read/write pipeline path w.r.t. clock alignment. We developed SPICE models for Pads, packages (BGA & TQFP), PCB tracks and SDRAM. Also VHDL models were written for synthesis and testbenches for verification of DLL clock distribution management.

Analog design, simulation and analysis of full custom analog blocks (0.25 micron CMOS) for a graphics display processor ASIC. The design work involved development of SPICE test suites for the analog silicon blocks which were PLLs for on-chip clock synthesis and clock-tree alignment, Pads for PCI/AGP 4X signalling system, and a Video-DAC for 10-bit composite video signal with pixel rate of 500 MHz.
