what's the Physical Design and Physical Verification

In ASIC Design ,what's the Physical Design and Physical Verification? Who can tell me and recommend some books for me? I just want to know the maim idear of the backend design for asic in more details. Thanks very much!

Physical design is refered to as the whole process from the netlist to GDSII, physical verification means the process of validation of the physical design, including DRC/ERC/LVS, and timing, signal integrity and power analysis etc.

You can find the latest pbulished books about physical design/verification by
searching on-line, using these key-words.

Sherwani, N. "Algorithms for VLSI Physical Design Automation" is good book that
gives a good perspective on this topic. You can download it from EDA book section.

Physical design refers to making layout for the design. This can include Full Custom (Layout for each transistor is made by hand) or semi-custom(Layout is automatically generated by a P&R tool from a netlist).

Physical Verification Refers to verifcation includes following two major two steps:
1.Design Rule Check
2. Layout for Schematic

1. DRC checks for if layout complies with Foundry rules that is if the layout will be manufacturable. Typically this will have width check,density check, spacing checks etc.

2. LVS checks if the layout matches with the reference. In case of full-custom the reference is spice netlist which is verified for functionality before getting into layout.

In case of semi-custom reference will be gate-level verilog netlist.

Hope this clarifies.

More on this you can clear it reading ASIC by Sebastian Smith.
