Step 3: Connect the Symbol

After instantiating the arm_processor symbol, you must connect the appropriate ports. To connect the ports of the arm_processor symbol to appropriate node and bus lines, position the symbol so that the following connections are made:

Connection from arm_processor Port: Connect To:

INPUT pin clk_ref clk_ref input port of arm_processor symbol

INPUT pin npor npor input port of arm_processor symbol

BIDIR pin nreset nreset bidirectional port of arm_processor symbol

masterhclk input port of arm_processor symbol Node line connecting INPUT pin HCLOCK to HCLOCK input port of pld_slave symbol

masterhready input port of arm_processor symbol HREADY output port of pld_slave symbol

masterhgrant input port of arm_processor symbol Node line connected to VCC symbol

masterhrdata[31..0] input port of arm_processor symbol Conduit connecting the HRDATA[31..0] output port of pld_slave symbol to the HRDATA[31..0] output bus

masterhresp[1..0] input port of arm_processor symbol HRESP[1..0] output port of pld_slave symbol

To continue the tutorial, proceed to Connect the Symbol (cont.).
