Cyclone IV GX Transceiver Starter Board, Clocks & Ports issue with HDL Coder (MATLAB)

Hello, 

 

i'm new in this forum but i have a problem to configure the HDL Workflow Advisor from MATLAB with the information from my FPGA (EP4CGX15BF14). 

 

In the attachement you can see a picture of the hdl workflow advisor and the fields i have to fill in. I don't use the MEX II, just the Cyclone IV GX FPGA. 

I have no idea after which clocks and ports i have to search in the manual (you can see the manual in the attachemnt). 

 

I am very thankful for help or some tips. 

 

best regards 

Niko

Hi, 

 

The attached image is low resolution. Could you attach high resolution version? Another option is zipping the image file and uploading it to here.

Hi, 

 

thx for the information. 

I added a zipped folder with the picture. Mostly i am interested in the clock and reset input ports/pins. Maybe i can not read the manual correctly but i am not sure if the ports/pins in the HDL_Workflow_Advisor.png  

are correct because i can't find pins just for the FPGA. 

 

best regards

You can find pin information called pin-out on altera.com. 

 

Go https://www.altera.com/products/fpga/cyclone-series/cyclone-iv/support.html 

Click 'Device Pin-Outs' 

Click 'Cyclone IV' 

Search 'EP4CGX15' and click Pin-Outs (XLS) 

Your device 'F14' package has 169 pins, so refer to column F 'F169'. I hate this translation :(  

 

Accoding to the spreadsheet, M7 pin is located in Bank B4, the function of the pin is CLK14 or DIFFCLK_6p. This is the best choice for clocks. I always uses differential I/O standard for clocks to avoid unexpected behavior caused by glitch on the clock, so I use DIFFCLK_*p pins. 

D10 is a general I/O pin, it should be good. 

R1 and R4 cannot be found in the spreadsheet. They must be changed to proper pin locations. 

 

I hope this helps you.
