Slave BFM Configuration
April 2014
A slave BFM has configuration fields that you can set via the set_config() function to configure
timeout factors, setup and hold times, and so on. You can also get the value of a configuration
field via the get_config() procedures. Table 9-2 describes the full list of configuration fields.
Table 9-1. Slave BFM Signal Width Parameters
Signal Width Parameter Description
AXI4_ADDRESS_WIDTH Address signal width in bits. This applies to the
ARADDR and AWADDR signals. Refer to the AMBA
AXI Protocol Specification for more details. Default: 32.
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.
