Hello,i would like to have the two orthoghonal modes TE10 TE01 and shift them 90 degrees to create circular polarization
in the CST menu i can only choose the number of modes but i cant know which modes specificly will be generated.I can choose the polarization angle

Hai, iam but familier with PIC programming, But this time one issue is giving me a big headache.
I am using PIC12F1840, i am not able to get output on RA4.
It simply gives zero volt, When i attach a 10k pullup It constantly gives me 5v.
i have set TRISPIN, I have disabled adcon etc..

No. 0 downto -1 is legal VHDL, and is a null range - ie. the loop doesnt get entered.
At least I know Quartus will work just fine. I cant speak for ISE or Vivado (though I suspect Vivado should work, but ISE you'll have to try it. Its had problems with null range vectors in the past)

Didn't really look at the library's source code but based on what it says about the gate time, you cant get 0.01 Hz resolution using this library.
