General description:

The slave interface svt_atb_slave_if defines the ATB signals appropriate for a single port, along with the modports needed for the ATB slave and monitor VIP. Debug signals and a debug modport are also defined. The debug port provides useful information for debugging.

Clock signal description:

Signal Name	Signal Description
atclk	If all ATB interfaces in the system are expected to run on a different clock, user can use the atclk signal in the port interfaces. Set the configuration parameter svt_atb_system_configuration :: common_clock_mode to 0. In this case, connect the atclk signal in each port interface to the appropriate port specific clock in the testbench.

Debug port description:
In active and passive mode, the VIP assigns a unique number to each transaction. This number is also displayed in the messages issued by the VIP. The debug port reflects this unique transaction number. This makes it easy to fnd a particular transaction on the waveforms, by looking at the debug port signals. For example, if messages mentions that there is a error on transaction #100, used can jump to value #100 on debug port signals, to find the transaction.

Signal Name	Signal Description
read_addr_xact_num	Transaction number on read address channel. Used in active mode.

ATB signal description:
The names of the signals match the names specified in the ATB specification. Please refer to the ATB specification for specific description of any of the signals.

General description:

ATB VIP provides the SystemVerilog interface which can be used to connect the VIP to the DUT. A top level interface svt_atb_if is defined. The top level interface contains an array of master & slave interfaces. By default, 16 master and 16 slave interfaces are defined in the top level interface. Currently, the maximum master and slave interfaces supported is 128. The number of master and slave interfaces in top level interface can be controlled using macros SVT_ATB_MAX_NUM_MASTERS_{0..128} and SVT_ATB_MAX_NUM_SLAVES_{0..128} respectively. For example, if you want to use 8 master interfaces and 10 slave interfaces, you can define following macros when compiling the VIP:

SVT_ATB_MAX_NUM_MASTERS_8

SVT_ATB_MAX_NUM_SLAVES_10
Please refer to User Guide section Overriding System Constants on how to provide these macro definitions to VIP.

Sub-interfaces:

Interface Name	Interface Description
svt_atb_master_if	Master Interface used by master VIP component
svt_atb_slave_if	Slave Interface used by slave VIP component

Clock signal description:

Signal Name

Signal Description

common_atclk

If all ATB interfaces in the system are expected to run on a common clock, user can use the common clock mode. Common clock mode can be selected by setting configuration parameter svt_atb_system_configuration :: common_clock_mode to 1. This is the default mode of operation. When common clock mode is used, connect common_atclk signal to the top level clock signal in the testbench. Pleae note that if you are using the Interconnect VIP component, you are required to always connect common_atclk signalto a clock in the testbench, as Interconnect VIP component internally uses this clock for its operation.

atclk

This signal belongs to the master and slave sub-interfaces. If all ATB interfaces in the system are expected to run on a different clock, user can use the atclk signal in the port interfaces. Set the configuration parameter svt_atb_system_configuration :: common_clock_mode to 0. In this case, connect the atclk signal in each port interface to the appropriate port specific clock in the testbench.

Clock connection examples:

Usage with common clock:
assign atb_if.common_atclk = SystemClock;

Usage with port specific clock:
assign atb_if.master_if[0].atclk = master_clk;
assign atb_if.slave_if[0].atclk = slave_clk;

Interface signal connections:

If master VIP is active, then connect DUT slave port signals to master interface:
assign atb_if.master_if[0].atvalid = DUT_slave_intf.atvalid;

If master VIP is passive, then connect DUT master port signals to master interface:
assign atb_if.master_if[0].atvalid = DUT_master_intf.atvalid;

If slave VIP is active, then connect DUT master port signals to slave interface:
assign atb_if.slave_if[0].atready = DUT_master_intf.atready;

If slave VIP is passive, then connect DUT slave port signals to slave interface:
assign atb_if.slave_if[0].atready = DUT_slave_intf.atready;
