求教v2lvs参数的一些问题

zzallok

v2lvs 中 -lsr和-lsp两个选项有何区别。
当我使用-lsp  bmr_ram8x72.cdl时候,会出现warning：nse_3360_top/cam_control_top_bmr_top_bmr_ram8x576_bmr_ram7 call port Q not declared in module bmr_ram8x72

当我使用-lsr  bmr_ram8x72.cdl时候,则没出现warning。

没太理解这两条的区别在哪。
· -lsp spice_library_file
Specifies SPICE library file name using pin mode. The SPICE file is parsed for
interface configurations. Pins with pin select ([ ]) annotation are kept as
individual pins using escaped identifiers.
· -lsr spice_library_file
Specifies SPICE library file name using range mode. The SPICE file is parsed
for interface configurations. Pins with pin select ([ ]) annotation are assembled
into Verilog ranges.

求大家给些指点啊！

   个人认为 ，lsp把pin bus 分离成独立的Pin。
