Schematic Capture : Schematic Settings
DRC Settings
DRC executes a design layout check so that schematics are easier to view.
By setting Clearance Values such as for detecting component collision, detecting overlapping with different Net wiring, and detecting the distance between components and attributes, it is possible to prevent mistakes.
For more details about opening the Schematic Settings screen, refer to About Schematic Settings.
Error Type
The following are the types of errors that can be configured.
| Item | Content |
|
Error |
When there is a problem when running DRC, the result becomes an Error. |
|
Warning |
When there is a problem when running DRC, the result becomes a Warning. |
|
OFF |
Even when there is a problem when running DRC, the result is not shown. |
DRC Check Contents
The following will explain the Check Contents of DRC Settings and their details.
- Clearance
- Distance
- Design Instructions
Clearance
Clearance is for checking whether objects overlap (distance check). When too close according to the settings, it is detected as an error.
When 0 is specified, no check is performed.
| Overlap of components. |
|
Error Check Type: Clearance Violation (Component to Component) When two components are closer to each other than the set clearance value, an error occurs. |
|
|
| Overlap of the component and the wire. |
|
Error Check Type: Clearance Violation (Component to Wire)
|
|
|
| Overlap of wires. |
|
Error Check Type: Distance Violation (Wire to Wire) When two wires are closer to each other than the clearance value, an error occurs. |
|
|
| Overlap of texts. |
|
Error Check Type: Distance Violation (Text to Text) When two texts are closer to each other than the clearance value, an error occurs. |
|
|
| Overlap between the text and other objects. |
|
Error Check Type: Distance Violation (Text to Others) When a text and another object are closer to each other than the clearance value, an error occurs. |
|
|
Distance
Configures the distance setting.
Distance is the distance check between objects.
When the distance is over the set value, an error occurs.
| Distance between components and component attributes. |
|
Error Check Type: Distance Violation (Component to Attribute) When the distance between a component and component attribute is over the set value, an error occurs. |
|
|
| Distance between pins and pin attributes. |
|
Error Check Type: Distance Violation (Pin to Pin Attribute) When the distance between a pin and pin attribute is over the set value, an error occurs. |
 |
Design Instructions
Configure settings for PCB Design Instructions.
Confirms whether a check is placed for the "Checked" item in the PCB Design Instructions.
If a check is not placed, an error occurs.
| Unconfirmed design instructions. |
|
Error Check Type: Design Instructions Unconfirmed (Component), Design Instructions Unconfirmed (Netlist), Design Instructions Unconfirmed (Others) If a check is not placed for "Checked" in Design Instructions, an error occurs. |
