quartus和xilinx ise两个环境中编辑的verilog文件互相兼容吗 [复制链接]

今天把quartus中语法检查成功了verilog文件复制到xilinx ise环境中竟然报语法错误了。不知道为什么。想问下大家两个环境中的verilog语法标准还不同吗

复制, 成功

 看不出来你的代码有语法错误！ 是不是你的ISE 软件破解有问题，造成这个结果！  详情 回复 发表于 2012-5-25 13:17

我是CTRL+A,CTRL+C然后CTRL+V复制的。同样编译不同过。用的ISE13.4

ISE的语法要求比QUARTUS严格，造成这个现象可能是你的verilog里面的语法不够严格。在quartus可能是告警，但在ISE里面可能报错。
