This article introduces what the memo of IIO plan command based on ICCI is like, the content is very detailed, interested friends can refer to, hope to be helpful to you.

Create bump array based on the memo of ICCII's IO plan

Use the command create_bump_array

IO ring + corner cell

In fact, it's easy to use create cell and move it manually, just once anyway. Just read it later by reading def.

IO constraints

Usually the power pad is calculated according to the spare position in advance. Exactly where to put it has been decided. It is rare to use this tool to automatically add power pad. If it is pad limit, put less power io, if it is the number of core limit,power io can be appropriate more.

Matching type

Pad and bump are matched by create_matching_type and add_matching_type. The tool will match in the pad and bump of the same matching type, using the nearest principle.

Special matching type

For example, PG net's bump&pad is one-to-many, many-to-many:

MarkRDL preparation

First create the routing rule. Second, set the routing angle to 45 °

Special RDL wound adjacent routesplit routedifferential route

Differential winding so that the length of the two windings is the same.

Paralell route (differential)

The winding length is equal, but try to have a longer parallel part.
