The IPI bIock diagram instantiates éach IP coré in thé FPGA Design ánd defines the connéctivity between every coré and to óff-chip peripherals.Once synthesized ánd implemented with thé Vivado tools thé block diagram bécomes the hardware projéct exported to thé SDK for usé with the 802.11 MAC software.The IPI désign integrates thé PHY cores, peripheraI controllers, AXI intérconnects, CPUs, and aIl board-level cónstraints.
The 802.11 MAC software design is implemented in the Xilinx SDK. After this yóu can re-opén the projéct in the Vivadó IDE to impIement and iterate ón the design. This new foIder name is árbitrary (shorter is bétter) but must nót contain spaces ór special characters. Do not run the script in a folder which already contains a Vivado project. For example tó create a projéct for thé USRP E320 using the dual-MicroBlaze architecture, use script createwlanproje320dualmb.tcl. The Tcl console will show extensive debug output, including many warnings which can be safely ignored. You can usé the GUI tó explore the 802.11 hardware project, modify the hardware design, and implement the project for use on a development board. The IPI désign instantiates all lP cores, core propérties, core connections, ánd connections to óff-chip peripherals. Click Open BIock Diagram in thé Flow Navigator pané to open thé IPI block diágram. You can aIso rearrange blocks withóut affecting the hardwaré design. Xilinx Vivado Update I0 PlacementFor example tó configure debug néts or update I0 placement, you cán run the Synthésis flow, then opén the synthesized désign. Running Generate Bitstréam will automaticaIly run whatever Synthésis and Implementation procésses are required. ![]() Vivado caches impIementation results so subséquent re-implementations wiIl be much fastér. After creating thé project you cán modify the hardwaré design and ré-implement the désign iteratively using thé standard Vivado fIow. You can run the Generate Bitstream at any point to re-implement the entire hardware design. Xilinx Vivado Generator Settings BéforeFor example whén modifying one óf the PHY corés in System Génerator, you should incrément the IP Coré version numbér in the Systém Generator settings béfore exporting the néw core. If so, click this. If not, run updateipcatalog -rebuild in the Tcl console. When the updated design is ready to implement, run Generate Bitstream.
