What does VLSI stand for?
VLSI stands for Very Large Scale Integration — the process of combining millions to billions of transistors onto a singl…
What is the difference between ASIC and FPGA?
An ASIC is a chip custom-built for one specific function and can’t be changed after manufacturing, while an FPGA is a re…
What is the difference between front-end and back-end VLSI design?
Front-end VLSI design covers logical design — writing and verifying the chip’s functional behavior — while back-end desi…
What is Static Timing Analysis (STA) in VLSI?
Static Timing Analysis is a method for verifying a chip’s timing without running simulations — it mathematically checks …
What is the difference between synthesis and place-and-route?
Synthesis converts RTL code into a gate-level netlist of logical components, while place-and-route takes that netlist an…
