ERROR的描述如下:
**ERROR: (TECHLIB-9067): (block starting at: 1068) Missing rise delay value for the path from pin CLKB to pin QB[127:0] in the cell sadglsmh4h2p16x128m1b1w1c0p0d0t0s10. Path is not generated ...The data in the timing library is incomplete. This can result in a loss of accuracy during delay calculation.

在之前也有了关于cell_rise和cell_fall的定义了:
