Programming the power Monitor

[Altera_Forum]

Hi, 

 I am working on the Cyclone III LS dev kit. I am using the Power Monitor software included into Quartus in order to measure power consumption. The software is very simple and is working well.  But, in order to develop an automated test bench, I am looking for API for power consumption measurement.  Is it possible to measure the power consumption from Java or C/C++ language ?  Maybe the best solution is to measure directly across the shunt resistors on the dev board with my digitizer.  Thanks a lot  Mickael

You can use system-console to automate it. 

 For more information about the system-console, please take a look at  http://nioswiki.com/systemconsole   You can do like this   set vj [ lindex [ get_service_paths sld ] 0 ]  You need to find out something like this by changing the last digit. /connections/USB-Blaster on localhost [USB-0]/EPM2210@2/[MFG:110 ID:8 INST:0 VER:0]  You need to try few times to get the access to the power monitor. set vj [ lindex [ get_service_paths sld ] 0 ] set vj [ lindex [ get_service_paths sld ] 1 ] set vj [ lindex [ get_service_paths sld ] 2 ] and so on…it will be depending on the FPGA design. If the FPGA has jtag node, it will be changed. If FPGA does not have any jtag node in it, you’ll need to find the  [MFG:110 ID:8 INST:0 VER:0]  [MFG:110 ID:8 INST:123 VER:0] is used for configuration [MFG:110 ID:8 INST:124 VER:0] is used for clock control for some other boards.    After finding out the node, open the service by typing open_service sld $vj   Now you need to select which power rail to read from sld_access_ir $vj 2 2 sld_access_dr $vj 4 1 3   The first line is the command to set the read address. The second line is the command to value of address. In this example, setting address(rail) to 0x3 If you want to set to address to 0x06, then  sld_access_ir $vj 2 2 sld_access_dr $vj 4 1 6   Now start reading power data You need to change the command to read command by typing sld_access_ir $vj 1 2  Read 16 bits of power data by typing sld_access_dr $vj 16 1 [list 0x00 0x00 ]   The [list 0x00 0x00 ] is feeding dummy data to push jtag data out.    If you want to read address 0 to 3 then  sld_access_ir $vj 2 2 sld_access_dr $vj 4 1 0 sld_access_ir $vj 1 2 sld_access_dr $vj 16 1 [list 0x00 0x00 ] sld_access_ir $vj 2 2 sld_access_dr $vj 4 1 1 sld_access_ir $vj 1 2 sld_access_dr $vj 16 1 [list 0x00 0x00 ] sld_access_ir $vj 2 2 sld_access_dr $vj 4 1 2 sld_access_ir $vj 1 2 sld_access_dr $vj 16 1 [list 0x00 0x00 ] sld_access_ir $vj 2 2 sld_access_dr $vj 4 1 3 sld_access_ir $vj 1 2 sld_access_dr $vj 16 1 [list 0x00 0x00 ]  You’ll be able to read them.  Here is the address and the data  "0000" average_volt;  "0001" average_amp;  "0010" average_watt;  "0011" max_volt;  "0100" max_amp;  "0101" max_watt;  "0110" min_volt;  "0111" min_amp;  "1000" min_watt;

Hi there, would you happen to know what the equivalent would be for the Cyclone V SoC Dev Kit?

I've created a script to read the current values from a command line, using system-console. It's been tested with the 'Cyclone IV GX Transceiver Starter Kit' and 'Cyclone IV GX FPGA Development Kit' boards, but it should be easy to adapt to other platforms.
