# Design General

#### This group consists of Design General constraints.
The rules are as follows:

- Negative plane islands oversize: Scales up the pad geometry before the check for Negative plane islands.
- Negative plane sliver spacing: Specifies spacing checks for Negative plane sliver spacing
- Testpoint pad to component spacing: Specifies spacing checks between the edges of testpoint pads and components.
- Testpoint location to component spacing: Specifies spacing checks between testpoint locations (center) and components.
- Testpoint under component spacing: Flags testpoints under components.
- Mech Pin to Mech Pin spacing: Specifies spacing checks between mechanical pins.
- Mechanical pin to conductor spacing: Attribute Name: MECH_PIN_TO_CONDUCTOR_SPACING
- Blind/Buried Via Separation: Blind/Buried Via layer separation.
- Pin to Route Keepout: Pin to route keepout verification mode
- Minimum metal to metal spacing: It is recommended to run this check when design is almost completed to avoid redundant DRC errors.
- Duplicate Drill Hole: Duplicate Drill Hole verification mode
- On-line Interlayer DRC On-line Interlayer DRC
