动量错误

嗨，我正在尝试使用我从客户收到的电路板上的动量在ADS中运行模拟。
不幸的是，板文件作为Altium文件交付给我，而不是作为cadence文件，所以我不得不使用ODB ++文件结构导入布局。
文件导入正常，堆栈看起来对我来说正确但在创建网格时我不断收到以下错误：--------------------------

我使用其他电路板的节奏几次完成了这个过程，我以前从未遇到过这些问题。
我怀疑我的问题在于我正在导入ODB ++文件，但我不确定。
我在这里想念的是什么？

  Hi,

I am trying to run a simulation in ADS using momentum on a board that I received from a customer. Unfortunately, the board files were delivered to me as Altium files and not as cadence file so I had to import the layout using the ODB++ file structure. The files import fine and the stack up looks correct to me but I keep getting the following error when creating the mesh:
  
---------------------------------------------------------------------------------- WARNING -------------------------------------------------------------------
Pin P1 is positioned on more than one edge.
Move the pin away from any unintended edges.

---------------------------------------------------------------------------------- WARNING -------------------------------------------------------------------
Pin P2 is positioned on more than one edge.
Move the pin away from any unintended edges.

---------------------------------------------------------------------------------- WARNING -------------------------------------------------------------------
Pin P4 is positioned on more than one edge.
Move the pin away from any unintended edges.

---------------------------------------------------------------------------------- WARNING -------------------------------------------------------------------
The port setup needed to be corrected:
Calibration will not be used for port "P3" (pin
"P3" is not on the edge between a conductive and
a nonconductive region).
-------------------------------------------------------------------------------
Generating mesh at 20 GHz...
Could not change process priority
S-parameter simulation
--- WARNING -------------------------------------------------------------------
The 2D port solver data is not available for  
thick conductor feedlines, using default values (50 Ohm)  
for the transmission line parameters.
-------------------------------------------------------------------------------
Automatic selection: direct compressed matrix solver
Using multi-threading (12 threads)
Matrix size: 36593 (reduced: 25123)
--- WARNING -------------------------------------------------------------------
Port 1 does not have an explicit reference pin,  
S-parameters may become unphysical at higher frequencies.
---------------------------------------------------------------------------------- WARNING -------------------------------------------------------------------
Port 2 does not have an explicit reference pin,  
S-parameters may become unphysical at higher frequencies.

---------------------------------------------------------------------------------- WARNING -------------------------------------------------------------------
Port 3 does not have an explicit reference pin,  
S-parameters may become unphysical at higher frequencies.

---------------------------------------------------------------------------------- WARNING -------------------------------------------------------------------
Port 4 does not have an explicit reference pin,  
S-parameters may become unphysical at higher frequencies.

I have been through this process several times using cadence with other boards and I have never run into these issue before. I suspect that my problem lies in the fact that I am importing ODB++ files but I am not sure. What am I missing here?

Regards,
Mike
