JTAG pin connections for MAX 10 FPGA

I am making a design using 10M08SAE144C8G. 

Below is the schematic reference I am using .

Here there is an embedded USB blaster design by default. But i dont want to use MAX V (CPLD) for it, instead I wasnt to use external USB blaster II. So the below is the jtag connector.

How the connections should go to FPGA pins. and what are things we need to take care while doing the schematic in the current file(schematic link above).

Can you please name the connection in terms of FPGA net names mentioned in the schematic like below.

Use the legend in the Pin Planner to find the JTAG pins for your device and connect appropriately in your schematic.

Sorry, I didn't get you. What legend in the pin planner you mean?

In the Pin Planner, choose to view the Legend from the View menu.  This explains all the symbols and colors on the pins, including highlighting the JTAG pins, so you can find the pins for your device.  You can also download pin files from the Intel web site, but I find it easier to see them directly in Pin Planner.

I am not sure, where this pin planner and legend if at. Maybe it is in different software.

I am using altium to design the board.

Below is the jtag connector header.

I am confused in connecting these JTAG J161A nd J161B pins to which pins of FPGA(10M08SAE144C8G).

Please help me with just these 10 connections of JTAG.

In Quartus, use the Pin Planner from the Assignments menu.

Thanks for your help. I just installed quartus, but the pins I have from jtag are not matching with all the FPGA JTAG pins. Is there a way to meet over webex to discuss in 10min? It would be really helpful to close this item quickly if we do so.

From the usb blaster there are 10 pins coming out like below.

But in these 10 pins, TCK, TDO, TMS, TDI are going to FPGA according to quartus pin planner. What to do with other pins coming from USB blaster?

Hi,


Sstrell was right. And you can also refer to MAX 10 pin connection guidelines:

Hi,


Have you refer to the USB blaster II userguide? It shows the connection for USB blaster ii. You can get it from below:

REgards,

Hi,
pin planner shows only JTAG signal pins, GND and VCC need to be also connected. For complete wiring of programming connector,
refer to MAX10 Device Handbook.

Additional pins are dedicated for AS memory programming, which has no function for MAX10.

What is AS?

And it is ok if we just use 4 pins from JTAG and connect them to FPGA. And leave remaining pins unconnected?

AS is active serial flash, used e.g. with Cyclone 10.

4 JTAG pins + GND + VCC
