What is feedthrough path?

Feedthrough blocks are the communication channels present at the top chip level with many hierarchical blocks to ensure smooth interaction between two or more blocks. Since it is like a channel between blocks so port positions and size are hard fixed.

What are the sequence of steps involved in the design flow of ASIC?

ASIC design flow is a mature and silicon-proven IC design process which includes various steps like design conceptualization, chip optimization, logical/physical implementation, and design validation and verification.

What is floorplanning in ASIC design?

Floorplanning is the art of any physical design. A well and perfect floorplan leads to an ASIC design with higher performance and optimum area. Floorplanning can be challenging in that, it deals with the placement of I/O pads and macros as well as power and ground structure.

What is a feedthrough cell?

A feedthrough is a conductor used to carry a signal through an enclosure or printed circuit board. Like any conductor, it has a small amount of capacitance. A “feedthrough capacitor” has a guaranteed minimum value of shunt capacitance built in it and is used for bypass purposes in ultra-high-frequency applications.

What is feed through cell?

Feedthrough helps here to wire a way out through the gate bypassing it, and connecting to nothing in the gate.

What is the difference between ASIC and FPGA design flow?

Even if you’re new to the field of very large-scale integration (VLSI), the primary difference between ASICs and FPGAs is fairly straightforward. An ASIC is designed for a specific application while an FPGA is a multipurpose microchip you can reprogram for multiple applications.

What is the main objective of floorplanning?

The objectives of floorplanning are to minimize the chip area and minimize delay. Measuring area is straightforward, but measuring delay is more difficult and we shall explore this next.

What is physical design in ASIC?

ASIC Physical design is sometimes called “back-end design” because it follows the “front-end” which is generally the first part of any ASIC design. ASIC Physical Design is the part where the design meets the physical world and therefore also the real world constrains, performance and behaviour.
