Package name: jsl/landpatterns/pad-island

Summary¶

Define a contiguous region of pads in a BGA matrix

Function	Description
PadIsland	Construct a PadIsland Using 1-indexed ranges.
to-pad-island (+ 1)	Convert a Grid Numbering Reference into a PadIsland
in-range?	Check if a row, column in the grid is a member of the Pad Island.

Define a contiguous region of pads in a BGA matrix

public defstruct PadIsland :
    columns: Range
    rows: Range

This allows us to define regions where the pads are either active or inactive.

Construct a PadIsland Using 1-indexed ranges.

public defn PadIsland (rows:Range, columns:Range) -> PadIsland

Users are likely going to find it easier to use 1-indexed values because that is more consistent with the rest of JITX.

Convert a Grid Numbering Reference into a PadIsland

public defn to-pad-island (grid:Grid-Numbering, r:IndexRef) -> PadIsland

grid: Grid-Numbering - Grid Numbering Scheme
r: IndexRef - Index Reference that indicates a particular pad to convert to a PadIsland
Returns PadIsland

public defn to-pad-island (grid:Grid-Numbering, s:String) -> PadIsland

Check if a row, column in the grid is a member of the Pad Island.

public defn in-range? (p:PadIsland, row:Int, column:Int) -> True|False
