configure variables such as timeout factors and setup and hold times. You can also get the value
of a configuration field via the get_config() function. Table 5-2 describes the full list of
configuration fields.
AXI4_RDATA_WIDTH Read data signal width in bits. This applies to the
RDATA signals. Refer to the AMBA AXI Protocol
Specification for more details. Default: 64.
AXI4_WDATA_WIDTH Write data signal width in bits. This applies to the
WDATA signals. Refer to the AMBA AXI Protocol
Specification for more details. Default: 64.
