Bases: prga.util.Object

Abstract base class for byte-addressable interfaces.

addr_width¶

Number of bits of the address bus.

Type:	`int`

data_bytes_log2¶

log2 of the number of bytes in the data bus.

Type:	`int`

class prga.integration.common._BaseFabricIntf(id_=None, ecc_type=<FabricIntfECCType.parity_even: 2>)¶

Bases: prga.integration.common._BaseIntf

Base class for fabric interfaces.

Parameters:	id (`str`) – Identifier of this interface ecc_type (`FabricIntfECCType`) –

ecc_type¶

class prga.integration.common._BaseIntf(id_=None)¶

Bases: prga.util.Object

Base interface.

Parameters:	id (`str`) – Identifier of this interface

_id¶

id_¶

Identifier of this interface.

This is used when the fabric has multiple of the same interfaces, such as when multiple memory interfaces are supported.

Type:	`str`
