Verifying Parameters between XPS and IP Integrator Designs for AXI Masters and Slaves in a Zynq Platform Processor-Based Design - 2024.1 English

Ensure that the XPS design has generated a netlist. This creates top-level IP wrapper files for every IP in the <xps_project>/hdl directory.

For example, <xps_project>/hdl /system_leds_4bits_wrapper.vhd contains the wrapper for AXI_GPIO in the EDK design. The important portions of the wrapper are the mappings to parameters, as shown below.

C_GPIO_WIDTH => 4,
C_GPIO2_WIDTH => 32,
C_ALL_INPUTS => 0,
C_ALL_INPUTS_2 => 0,
C_INTERRUPT_PRESENT => 1,
C_DOUT_DEFAULT => X"00000000",
C_TRI_DEFAULT => X"ffffffff",
C_IS_DUAL => 0,
C_DOUT_DEFAULT_2 => X"00000000",
C_TRI_DEFAULT_2 => X"ffffffff"

report_property [get_bd_cells axi_gpio_0]

From the report in the Tcl Console, the important lines contain C_, which are for parameters. The following example shows lines that are used for comparison.

CONFIG.C_ALL_INPUTS           string  false      true     0
CONFIG.C_ALL_INPUTS_2         string  false      true     0
CONFIG.C_ALL_OUTPUTS          string  false      true     1
CONFIG.C_ALL_OUTPUTS_2        string  false      true     0
CONFIG.C_DOUT_DEFAULT         string  false      true     0x00000000
CONFIG.C_DOUT_DEFAULT_2       string  false      true     0x00000000
CONFIG.C_GPIO2_WIDTH          string  false      true     32
CONFIG.C_GPIO_WIDTH           string  false      true     4
CONFIG.C_INTERRUPT_PRESENT    string  false      true     1
CONFIG.C_IS_DUAL              string  false      true     0
CONFIG.C_TRI_DEFAULT          string  false      true     0xFFFFFFFF
CONFIG.C_TRI_DEFAULT_2        string  false      true     0xFFFFFFFF

Comparing the parameters, all parameter values match except C_ALL_OUTPUTS and C_ALL_OUTPUTS_2, which are new parameters on the latest AXI GPIO IP for IP integrator.

If changes to parameters are necessary:

Double-click the IP instance in the block diagram and make the proper parameter changes to update the XCI file.

If you cannot find the parameters in the GUI:

1. Select the IP in the block diagram.
2. Select the Properties tab under Block Properties.
3. Expand Config and enter the value for the parameter.
4. Redo the report_property command and modify if necessary.
5. Click Validate Design to ensure no issues exist with the design.
