I had embarked on an exciting and challenging journey to design and optimize logic gates and multiplexers in Cadence. This project, part of our VLSI design coursework, required me to deepen my understanding of transistor-level design, circuit simulation, and layout optimization. Through meticulous placement and routing, I ensured efficient power consumption, minimal propagation delay, and DRC/LVS compliance, reinforcing my skills in custom digital circuit design.
I designed and optimized a two-input circuit with an inverter gate in Cadence, ensuring efficient layout, minimal delay, and DRC/LVS compliance for VLSI design. The cell width is 4.8 micrometer.
I designed and optimized an NAND gate in Cadence, ensuring efficient layout, minimal delay, and DRC/LVS compliance for VLSI design. The cell width is 9.6 micrometer.
I designed and optimized an NOR gate in Cadence, ensuring efficient layout, minimal delay, and DRC/LVS compliance for VLSI design. The cell width is 7.2 micrometer.
I designed and optimized an XOR gate in Cadence, ensuring efficient layout, minimal delay, and DRC/LVS compliance for VLSI design. The cell width is 16.8 micrometer.
