Re: ASIC Design Flow

I recommend the following book:
"Application-Specific Integrated Circuits - Addison Wesley"

You can find it if you connect to "".

If you want to know the phases in details, you should study different books. But i suggest you to read the above book. After that you can look for more books which explain each phase in details.

Regards,
KH

Re: ASIC Design Flow

ASIC Design flow includes the follwoing steps:

1. Design entry : Enter the design into an ASIC design system, i.e understand the design as

Full-Custom ASICs
Standard-Cell-Based ASICs
Gate-Array-Based ASICs
Channeled Gate Array
Channelless Gate Array
Structured Gate Array
Programmable Logic Devices
Field-Programmable Gate Array

2: ) Logic synthesis : Produce a netlist. : - a netlist is defined as the various interconnections well defined.

3: ) System partitioning : Divide a large system into ASIC-sized pieces.

4: ) Prelayout simulation : If the design functions correctly.

5: ) Floorplanning : Arrange the blocks of the netlist on the chip.

6: ) Placement : Decide the locations of cells iin a block.

7: ) Routing : Make the connections between cells and blocks.

8: ) Circuit Extraction : Determine the resistance and capacitance of the interconnection.

9: ) Postlayout simulation. Check to see the design still works with the added loads of the interconnect.

Ive attached a detailed document regarding ASIC Basics and DESIGN Flow

Hope its useful for u

with regards

Re: ASIC Design Flow

hi :

I think you can get " TSMC Reference Flow Release 5.0 " from tsmc .

TSMC Reference Flow Release 1.0 /2.0 is better
,ver3.0 or later focus on backend
