Hi,I have an IP block for a GTY transceiver that, since moving to the Linux tools, is bombing out with the following error:ERROR: [DRC UCIO-1] Unconstrained Logical Port: 16 out of 39 logical ports have no user assigned
1.问题描述 很多工程有些logic port,我们不想对它进行管脚约束,但是不约束在生成bit文件时会产生类似下面的错误 [DRC UCIO-1]UnconstrainedLogical Port: 10 out of 28 logical ports have no user assigned specific location constraint (LOC). This may cause I/O contention or incompatibility with the boar....
