What are hard macros?

What are hard macros?

Hard macros are macros that have a physical representation, and are delivered in the form of a GDSII file. As a result, hard macros are more predictable than soft macros in terms of timing, power, and area.

What is a macro in IC design?

Introduction. Macro-cells in the integrated circuits (10) design are large blocks which can be viewed as black-boxes. The logic and electronic behav- ior of these macro-cells are given but the inside structural description mayor may not be known.

What is macro in semiconductor?

Hard cores (or hard macros) are analog or digital IP cores whose function cannot be significantly modified by chip designers. These are generally defined as a lower-level physical description that is specific to a particular process technology.

What is macro cell in VLSI?

Abstract: A new methodology for designing VLSI circuits has been developed at Harris GSS. The methodology is based on the concept of parametric macro cells. A parametric macro cell is an MSI-level circuit which can be modified by a computer program to meet the needs of a particular design.

What is the difference between soft macros and hard macros?

A “soft macro” is a sub-unit of a chip (eg: a USB controller) that is presented as RTL code. Synthesis, placement and routing have not been done. A “hard macro” is a sub-unit of a chip that has been synthesized, placed and routed so that the designer gets it as a GDSII layout description.

What is hard and soft macros?

Hard macro, firm macro and soft macro are all known as IP (Intellectual property). They are optimized for power, area and performance. Soft macro is flexible for all type of ASIC implementation. Hard macro can be used in pure ASIC design flow, not in FPGA flow.

What is the difference between soft macro and hard macro?

What are macros ASIC?

Hard macro, firm macro and soft macro are all known as IP (Intellectual property). They are optimized for power, area and performance. They can be purchased and used in your ASIC or FPGA design implementation flow. Hard macro can be used in pure ASIC design flow, not in FPGA flow.

What is the difference between macro cells and small cells?

small cells: Macrocells provide low-frequency coverage for miles, while small cells provide high-frequency coverage for around 100 yards. Macrocells provide low-frequency coverage for miles, while small cells provide high-frequency coverage for around 100 yards.

What is a macro cell site?

A macrocell or macrosite is a cell in a mobile phone network that provides radio coverage served by a high power cell site (tower, antenna or mast). Generally, macrocells provide coverage larger than microcell.

What are soft and hard macros?

What are analog macros?

We offer various analog macros (data converter, power management, temperature sensor, analog front-end) for our customers’ development to address various applications including communication, image processing, sensors and control.
