prga.tools.bitgen.common module

class prga.tools.bitgen.common.AbstractBitstreamGenerator(context)

Bases: prga.util.Object

Abstract base class for bitstream generators.

Parameters:context (Context) –

_none = <object object>

_reprog_param = re.compile('(?P<name>\\w+)\\[(?P<high>\\d+):(?P<low>\\d+)\\]')

_reprog_value = re.compile("(?P<width>\\d+)'(?P<notation>[bdhBDH])(?P<value>[a-fA-F0-9]+)")

context

generate_bitstream(input_, output, args)

Generate bitstream without storing parsed data.

Parameters:

• input (str of file-like object) –
• output (str of file-like object) –
• args (Sequence [str ]) – Remaining arguments other than the ones specified in the common argument parser

parse_fasm(fasm)

Parse an FASM file. Calls AbstractBitstreamGenerator.set_bits, which must be implemented by a sub-class.

Parameters:fasm (str or file-like object) –

parse_feature(line)

Parse one FASM feature.

Parameters:line (str) – Returns: Return type:FASMFeatureConn or FASMFeaturePlain or FASMFeatureParam

set_bits(value, hierarchy=None, *, inplace=False)

Update bitstream with the specified value and hierarchy. Subclass may implement this method to use AbstractBitstreamGenerator.parse_fasm.

Parameters:

• value (ProgDataValue) –
• hierarchy (AbstractInstance) –

Keyword Arguments:  

inplace (bool) – If set, value may be modified in place.
