ESD Design Synthesis
1.1 ESD Design Synthesis and Architecture Flow
In the ESD design synthesis process, there is a flow of steps and procedures to construct a semiconductor chip [1–13]. In many cases, the floorplanning process is a function of the type of semiconductor chip. The following design synthesis procedure is an example of an ESD design flow needed for semiconductor chip implementations:
- I/O, Domains and Core Floorplan: Define floorplan of regions of cores, domains, and peripheral I/O circuitry.
- I/O Floorplan: Define area and placement for I/O circuitry.
- ESD Signal Pin Floorplan: Define ESD area and placement.
- ESD Power Clamp Network Floorplan: Define ESD power clamp area and placement for a given domain.
- ESD Domain-to-Domain Network Floorplan: Define ESD networks between the different chip domains area and placement for a given domain.
- ESD Signal Pin Network Definition: Define ESD network for the I/O circuitry.
- ESD Power Clamp Network Definition: Define ESD power clamp network within a power domain.
- Power Bus Definition and Placement: Define placement, bus width, and resistance requirements for the power bus.
- Ground Bus Definition and Placement: Define placement, bus width, and resistance requirements for the ground bus.
- I/O to ESD Guard Rings: Define guard rings between I/O and ESD networks.
- I/O Internal Guard Rings: Define guard rings within the I/O circuitry.
- I/O External Guard Rings: Define guard rings between I/O circuitry and adjacent external circuitry. ...
