Surface Analyzer

Surface Analyzer analyzes design errors for surface and symbols and creates a report to list all the findings
Surface Analyzer only provide analysis check, does not change layout content
Required to change line drawn copper surface to surface feature first

Open Surface Analyzer

In the Graphic Editor screen, select "Analysis" ，then select "Surface Analyzer" 。( 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

Max Size

Set max size for Surface design error，to be used with Mode

Mode

Set criteria for Surface size, value will be display as Problematic Surface and Small Polygon
X or Y: If Surface length or width are lower than Max Size value, it is considered a design error
Y and Y: If Surface length and width are lower than Max Size value, it is considered a design error
Area: If Surface area value is lower than Max Size ² ,it is considered a design error

Max Fold Length

Set max fold length for surface edge

Small Edge Length

Set minimum distance for surface edge

Apply To

All: Check all surfaces
Selected: Check selected surface

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 items：

Self-intersection in surface

Any two surface edge overlaps with each other

Self-intersection in symbol

Any two symbol edge overlaps with each other

Problematic Surface

Surface considered to be design error

Wrong Nesting for island

Overlapping islands on surface

Wrong Nesting for hole

Overlapping holes on surface

Small Polygon

Surface size smaller than allowed value, defined by Max Size

Small polygon in symbol

Symbol size smaller than allowed value, defined by Max Size

Fold

Surface with fold edge, defined by Max Fold Length

Fold in Symbol

Symbol with fold edge, defined by Max Fold Length

Small edge in surface

Surface with edge length design error, defined by Small Edge Length

Small edge in symbol

Symbol with edge length design error, defined by Small Edge Length

Run Surface Analyzer

Run Surface Analyzer (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 )

View Analysis Report

Click the " ＋ " button on the lower right to view analysis report( Command：chklist_ res_show )

Result Viewer Form will be opened after click on the " ＋ " button

Result Viewer Form

In Result Viewer Form, Severity report will be displayed based on selected layers

View Detected Error in the Layout

In Result Viewer Form, click " <-- " or " --> " to view each error entry in the layout (See example below)

Click "Show All" will highlight all the error spots in the layout(See example below)

View Result Histogram for Analysis

Select an error entry, click the bar icon on lower right to open Result Histogram

Command：chklist_ hist_close

Command：chklist_ hist_show
