getShapeOfNode

protected Poly[] getShapeOfNode(NodeInst ni,
                                boolean electrical,
                                boolean reasonable,
                                Technology.NodeLayer[] primLayers,
                                Layer layerOverride)

Method to return a list of Polys that describe a given NodeInst. This method overrides the general one in the Technology object because of the unusual primitives in this Technology.

Overrides:

getShapeOfNode in class Technology

Parameters:

ni - the NodeInst to describe.

electrical - true to get the "electrical" layers. This makes no sense for Schematics primitives.

reasonable - true to get only a minimal set of contact cuts in large contacts. This makes no sense for Schematics primitives.

primLayers - an array of NodeLayer objects to convert to Poly objects.

layerOverride - the layer to use for all generated polygons (if not null).

Returns:

an array of Poly objects.

getShapeOfArc

protected void getShapeOfArc(AbstractShapeBuilder b,
                             ImmutableArcInst a)

Fill the polygons that describe arc "a".

Overrides:

getShapeOfArc in class Technology

Parameters:

b - AbstractShapeBuilder to fill polygons.

a - the ImmutableArcInst that is being described.

isEasyShape

public boolean isEasyShape(ImmutableArcInst a,
                           boolean explain)

Tells if arc can be drawn by simplified algorithm FPGA arcs are not easy

Overrides:

isEasyShape in class Technology

Parameters:

a - arc to test

explain - if true then print explanation why arc is not easy

Returns:

false

readArchitectureFile

public void readArchitectureFile(boolean placeAndWire)

Method to read an architecture file and customize the FPGA technology. Prompts for a file and reads it.

Parameters:

placeAndWire - true to build the primitives and structures; false to simply build the primitives.

setWireDisplay

public void setWireDisplay(int level)

Method to set the wire display level.

Parameters:

level - 0 to show no wires; 1 to show active wires; 2 to show all wires.

setTextDisplay

public void setTextDisplay(boolean show)

Method to set the text display level.

Parameters:

show - true to see text, false to hide text.

programPips

public void programPips()

Method to program the currently selected PIPs.
