感谢解答。这是个单电源域应用,我没写upf。有一个给efuse供电的avdd,rtl中不带pg会报这个。
Information: Verilog connection found to PG pin u_pad_ring/u_AVDD/SVDD1ANP. The Verilog reader will use PG netlist mode. (UPF-711)
Note - message 'UPF-711' limit (1) exceeded. Remainder will be suppressed.
Error: The power pin VDD on the cell u_delay1 is unconnected. (UPF-581)
之后我就将rtl改成带pg的,我估计电源这里错了。我今天试了一下单独综合各个模块,都是可以的,从top综合就不行= =!
