Users can use the get_pins API to get the pins in an XSA file. These can be pins at a high level
Vitis [0]: pins = HwDesign.get_pins(hierarchical='true')
Vitis [0]: print(pins)
s_axi_aclk s_axi_aresetn s_axi_awaddr s_axi_awvalid s_axi_awready s_axi_wdata s_axi_wstrb s_axi_wvalid s_axi_wready s_axi_bresp s_axi_bvalid s_axi_bready s_axi_araddr s_axi_arvalid s_axi_arready s_axi_rdata s_axi_rresp s_axi_rvalid s_axi_rready gpio_io_o ACLK ARESETN ...
Similar to the cells object previously, users can return the pin properties
Vitis [0]: pins[0].report_property()
Property Type Read-only Value
CLASS string true port
CLK_FREQ string true 99990005
DIRECTION string true I
INTERFACE bool true 0
IRQID string true
IS_CONNECTED bool true 1
LEFT string true
NAME string true s_axi_aclk
POLARITY enum true
RIGHT string true
SENSITIVITY enum true
TYPE enum true clk
Users can use this to make a better filter. For example, if users wantred to return all clk pins
Vitis [0]: clk_pins = HwDesign.get_pins(hierarchical='true',filter='TYPE==clk')
Vitis [0]: print(clk_pins)
s_axi_aclk ACLK S00_ACLK M00_ACLK slowest_sync_clk maxihpm0_fpd_aclk pl_clk0
Users can return the pins on a specfic object such as the axi_gpio cell used above
Vitis [0]: print(cells[0])
axi_gpio_0
Vitis [0]: axi_gpio_pins = HwDesign.get_pins(of_object=cells[0],filter='TYPE==clk')
Vitis [0]: print(axi_gpio_pins)
s_axi_aclk
Filtering on the TYPE pin property is also useful to find all interrupt pins
Vitis [0]: axi_gpio_pins = HwDesign.get_pins(of_object=cells[0],filter='TYPE==INTERRUPT')
Users can filter on the pin DIRECTION && TYPE
Vitis [0]: axi_gpio_in_clks = HwDesign.get_pins(of_object=cells[0],filter='DIRECTION==I&&TYPE==clk')
Vitis [0]: print(axi_gpio_in_clks)
s_axi_aclk
