| + | < | ||
| + | // Warning: Could not identify the data path input for the library cell containing | ||
| + | // the memory element at /dff115/D (382.4). X-bounding logic cannot be inserted in | ||
| + | // the scan path so this is a fatal error. This could be caused by missing | ||
| + | // pin constraints and/or scan_enable connections. (XB2-1) | ||
| + | </ | ||
| + | 一个解法是给对应的register cell换成带scan cell的，要么把它的SE悬空，要么把它case为1，即能在它前面正常插入x-bounding. | ||
