I'm using Altera FPGA for the first time. The Part is Cyclone V 5CEFA7F23 and I'm wondering if this part has a on die temperature sensor that I can read over JTAG.I've gone thru the datasheets and seems like Cyclone V does not have one but wondering if anyone knows since sometimes some information is not in the datasheets. If there is one, how might I read the temperature? Thanks.
I'm pretty sure there isn't one. There are sensors in Stratix IV, Stratix V, Arria V, Arria 10, but not in Cyclone V. Temperature sensors are grayed out in the IP Catalog. Sensor IP blocks are named stratixv_tsdblock, arriav_tsdblock, twentynm_tsdblock, etc. and an attempt to create a "cyclonev_tsdblock" results in an error.
I suppose one could always glue e.g. a DS18B20 to the surface and hook it up to a vacant GPIO pin. It would interfere with a heatsink, and the measurements might be off, but it costs pennies and it is straightforward to hook up.
