主页 > 支持 > 软件 > 综合工具 > LeonardoSpectrum > Example of Creating a Black Box for a Verilog HDL Custom Megafunction Variation with the Leonardo Spectrum Software 打印此页 发送此页 Example of Creating a Black Box for a Verilog HDL Custom Megafunction Variation with the Leonardo Spectrum Software To specify that the LeonardoSpectrum software should treat the cam_wrapper_v.v file, which you created in Example of Creating a Verilog HDL Custom Variation of the altcam Function, as a black box, refer to the following code sample from the top-level design file. In this example, the top-level design file is camsource.v. To modify the source code for the camsource.v file to define the module name and port type and to specify that the module is a black box, you can use the cam_wrapper_bb.v empty module declaration and add it to the camsource.v top-level design file as shown in the following code sample: Camsource.v module camsource ( pattern, wraddress, wren, wrx, wrxused, wrdelete, inclock, inclocken, inaclr, maddress, mfound, mcount, rdbusy, wrbusy); ); input [31:0] pattern; input [4:0] wraddress; input wren; input [31:0] wrx; input wrxused; input wrdelete; input inclock; input inclocken; input inaclr; output [4:0] maddress; output mfound; output [4:0] mcount; output rdbusy; output wrbusy; cam_wrapper_v U1 (.pattern(pattern), .wraddress(wraddress), .wren(wren), .wrx(wrx), .wrxused(wrxused), .wrdelete(wrdelete), .inclock(inclock), .inclock(inclock), .inclocken(inclocken), .inaclr(inaclr), .maddress(maddress), .mfound(mfound), .mcount(mcount), .rdbusy(rdbusy), .wrbusy(wrbusy)); endmodule module cam_wrapper_v ( pattern, wraddress, wren, wrx, wrxused, wrdelete, inclock, inclocken, inaclr, maddress, mfound, mcount, rdbusy, wrbusy); input [31:0] pattern; input [4:0] wraddress; input wren; input [31:0] wrx; input wrxused; input wrdelete; input inclock; input inclocken; input inaclr; output [4:0] maddress; output mfound; output [4:0] mcount; output rdbusy; output wrbusy; endmodule 给本页评分
