OpenFPGA Arch Parser

class util.openfpga_arch.OpenFPGA_Arch(vpr_arch, openfpga_arch, layout: None)

This is an architecture parser which parses the VPR and OpenFPGA XML files and provides easy interface APIs

Note

The idea here is not to parse complete architecture and rebuild the openfpga and VPR mapping

Methods:

__init__
get_width	Return width of selected layout
get_height	Return height of selected layout
get_layouts	Returns the dictionary of avaialble layouts in the architecture
set_layout	Set specific layout as primary layout
is_homogeneous	Checks if the device is homogeneous device or heterogenous
get_hetero_columns	Returns columns numbers of given heterogenesous pb_type
get_hetero_rows	Returns row numbers of given heterogenesous pb_type

Attributes:

pb_types	Returns list of pb_types in the architecture
tiles	Returns list of tiles in the architecture
layout	Returns selected layout name

__init__(vpr_arch, openfpga_arch, layout: None) → None

property pb_types

Returns list of pb_types in the architecture

property tiles

Returns list of tiles in the architecture

property layout

Returns selected layout name

get_width()

Return width of selected layout

get_height()

Return height of selected layout

get_layouts()

Returns the dictionary of avaialble layouts in the architecture

Returns

Available layouts as a key and (width, height) as a value of each key

Return type

dict

set_layout(layout_name)

Set specific layout as primary layout

is_homogeneous()

Checks if the device is homogeneous device or heterogenous

if layout section contains anything other than corner, periphery and fill the device is consider as a homogeneous

get_hetero_columns(pb_type)

Returns columns numbers of given heterogenesous pb_type

get_hetero_rows(pb_type)

Returns row numbers of given heterogenesous pb_type
