Rout Layer Checks

Rout Layer Checks

Rout Layer Checks analyzes rout layers for design errors, specifically for line and arc features, feature with .comp attribute is included.

Open Rout Layer Checks

In Graphic Editor screen, select "Analysis" ，then select "Rout Layer Checks" 。( Command：chklist_single )

Parameters

Parameters values can be changed in the respective fields and saved in ERF
All values and settings shown in this guide is by default
Parameters interface are shown below ：

Parameters

Layer

Select layer to run analysis

Default Tool Size

Set default tool size, features with .rout_tool attribute will use attribute value instead

Check Pilot Holes On Plunge

Detect Pilot Holes, pilot hole pad has the .pilot_hole attribute

Apply to

All	Analyze all features in the layer
Selected	Analyze selected feature

Set Range

Command：chklist_ erf_range

Set range value for each analysis check items
There are three types of analysis result: Critical, Warning or Safe
Default setting is avaialble for all parameters
Value can be changed in respective fields, and saved in ERF
See below picture for the Range interface：

Range

Small Arc

Set analysis result range for arc feature radius smaller than half the size of rout tool

Short Line

Set analysis result range for line feature length shorter than half the size of rout tool

Short Arc

Set analysis result range for arc feature length shorter than half the size of rout tool

Intersection

Set analysis result range for any rout feature in contact with each other

Too Narrow

Set analysis result range for two features with not enough spacing in the same chain

Unfinished chain

Set analysis result range for connected features with chain attribute issues
Issues to be detected：
- Not all features has the .comp or .rout_chain attribute
- Features in the same chain has different comp / feed / speed value

Unprocessed chain

Set analysis result range for detecting connected features without .rout_chain or rout chain relevant attributes

Unclosed Gap

Set analysis result range for detecting nearby but not connected features, with spacing value higher Min Unclosed Gap ] and lower than Max Unclosed Gap

Miss Pilot Hole

Set analysis result range for detecting pilot holes in chain, option for Check Pilot Holes On Plunge has to be turned on

Problematic Intersection

To be continued.

Zero Length Line

Set analysis result range for detecting line feature with 0 length

Duplicate Surface

Set analysis result range for detecting duplicate surface

Advance Variables

Parameters values can be changed in the respective fields and saved in ERF
All values and settings shown in the examples is by default
Parameters interface are shown below ：

Intersect check tolerance

Set tolerance value for Intersection analysis

Min Unclosed Gap

Set minimum gap value for Unclosed Gap analysis

Max Unclosed Gap

Set maximum gap value for Unclosed Gap analysis

Zero length line limit

Set minimum value for Zero Length Line analysis

Run Rout Layer Checks

Run Rout Layer Checks after set up the parameters (Command：chklist_run)
Three buttons in the lower interface, each button runs the module at different area range
- Global ：Analyze all features in the layer ( Command：chklist_cupd )
- Screen ：Analyze all features in the screen display area( Command：chklist_cupd )
- Profile ：Analyze all features in profile frame( Command：chklist_cupd )
