       - HPC would be interesting for some applications like high-speed
         ADCs where you need to go massively parallel to avoid too high
         bandwidth requirements on the data lines.
-  - Makes that large FPGA should be used
+      - Test and debug using a [Xilinx FMC-XM105 debug
+        card](https://www.xilinx.com/products/boards-and-kits/hw-fmc-xm105-g.html)

+    pins are available as much as possible. For a smaller FPGA at least
+    the LPC pins on the HCP connector will be available.
   - HPC: need new tests tools for production test
 
 Price idea:
 
   - LPC ($12.68/connector), n layers, Kintex 70T FPGA
-  - HPC ($20.40/connector), n+2 layers, Kintex 325T FPGA -\> 325T? 160T
-    not large enough?
