up_down door 这两个文件都不在Counter 这个工程内 也就是这三个工程文件相互独立了，没有关联。你应该把 up_down door 放在Counter 这个Project下编译仿真。
I am synthesizing a vhdl netlist with pacakge declarations .The verilog o/p netlist has PORT names expanded with record elelents . Is there a method where port names are output in the verilog as it is "without" the record elements.

It's clear, that the physical SDA line should be driven in an open drain manner, either '0' or 'Z'. Also, there's only one physical open drain driver in the FPGA I/O cell. A tri-state respectively inout port can be nevertheless connected through the design hierarchies, if you do ...
