Class GlobalMap

java.lang.Object
  |
  +--org.opencores.mapping.GlobalMap

public class GlobalMap
extends java.lang.Object

Collection of functions, that allows global (special) node mapping.

See Also:: NodeGlobal

Field Summary
`private Graph`	`g` graph we are working on
`static java.lang.String`	`NAME_PIO_CLK` Name definition for PIO clock.
`static java.lang.String`	`NAME_WB_CLK` Name definition for Wishbone clock.

Constructor Summary
`GlobalMap(Graph g)` Constructs new Global mapper

Method Summary
`void`	`mapGCLK0()` Finds best net that could have use of `GLCK0` and it assigns to `NetGlobal GLCK0`.
`void`	`mapGCLK1()` Finds best net that could have use of `GLCK1` and it assigns to `NetGlobal GLCK1`.
`void`	`mapGRST()` Finds best net that could have use of `GRST` and it assigns to `NetGlobal GRST`.
`void`	`mapGSET()` Finds best net that could have use of `GSET` and it assigns to `NetGlobal GSET`.
`void`	`mapLUT0()` Converts all LUT0s, that don't drive FF.DATA into NodeGlobal.
`void`	`mapping()` Does complete global net mapping on graph `g`
`void`	`mapPIO_CLK()` Searches for port named PIO_CLK and assigns it to SR.
`void`	`mapWB_CLK()` Searches for port named WB_CLK and assigns it to SR.

Field Detail

NAME_WB_CLK

public static final java.lang.String NAME_WB_CLK

Name definition for Wishbone clock.

NAME_PIO_CLK

public static final java.lang.String NAME_PIO_CLK

Name definition for PIO clock.

g

private Graph g

graph we are working on

Constructor Detail

GlobalMap

public GlobalMap(Graph g)

Constructs new Global mapper

Method Detail

mapLUT0

public void mapLUT0()

Converts all LUT0s, that don't drive FF.DATA into NodeGlobal. This function should be called after optimal mapping and before SPC and GPC groupping.

SPC, GPC and FF mapping should link to global nets instead of assigning null, to reduce complexity.

mapGCLK0

public void mapGCLK0()

Finds best net that could have use of GLCK0 and it assigns to NetGlobal GLCK0.

Parameters:: g - graph to work on

mapGCLK1

public void mapGCLK1()

Finds best net that could have use of GLCK1 and it assigns to NetGlobal GLCK1.

Parameters:: g - graph to work on

mapGRST

public void mapGRST()

Finds best net that could have use of GRST and it assigns to NetGlobal GRST.

Parameters:: g - graph to work on

mapGSET

public void mapGSET()

Finds best net that could have use of GSET and it assigns to NetGlobal GSET.

Parameters:: g - graph to work on

mapPIO_CLK

public void mapPIO_CLK()

Searches for port named PIO_CLK and assigns it to SR. NOTE: should be called before IOCMap

mapWB_CLK

public void mapWB_CLK()

Searches for port named WB_CLK and assigns it to SR. NOTE: should be called before IOCMap

mapping

public void mapping()

Does complete global net mapping on graph g
