it report there has no lef pin matched U_ISO_UNITS/U_ISO_CSI_TESTDOUT5/ISO , that is to say , all the listed pin can not been found , but they are at there , why report can not been found in the design ?

没人理我啊?

一般buffer tree是自动 产生的，根据需要
而有可能你这个是power domain引起的，比如dont touch属性等，

是的，bts_spec.tcl 是自动产生的，但是没有插入buffer形成tree， 那么是net 的dont_touch 还是cell 的dont_touch 造成的呢，或者是module 的dont_touch 属性造成的?

是不是LeafPorts啊，用get_ports试试看看
