1. 设计顶层测试文件时报错误!
Started : "Behavioral Check Syntax".
Determining files marked for global include in the design...
Running vlogcomp...
Command Line: vlogcomp -work isim_temp -intstyle ise -prj {E:/FPGA Projects/Test1/TestFig_stx_beh.prj}
Determining compilation order of HDL files
Analyzing Verilog file "E:/FPGA Projects/Test1/Source/Module1.v" into library isim_temp
ERROR:HDLCompiler:806 - "E:/FPGA Projects/Test1/Source/Module1.v" Line 1: Syntax error near " ".
WARNING:HDLCompiler:1591 - "E:/FPGA Projects/Test1/Source/Module1.v" Line 1: Root scope declaration is not allowed in verilog 95/2K mode
Verilog file E:/FPGA Projects/Test1/Source/Module1.v ignored due to errors
Process "Behavioral Check Syntax" failed
Process "Behavioral Check Syntax" failed
找了各种方法,查了各种语法,无果。。。
最后问题找到:语法没写错,公司电脑ISE软件加密问题!!!坑爹。。
果断弃之,在外部编辑器中写代码!
2. 报错:Signal count[24] in unit led1 is connected to following multiple drivers:
原因:在多个always块里对同一个reg型变量进行赋值;
3. 报错:Port connections cannot be mixed ordered and named
原因:语法问题,查找! 比如实例化时 少了.
