Regular ContributorHi Uday,
Refresh connections after selecting the checkbox "Ignore mismatched system ID" and "Ignore mismatched system timestamp.
under Run->run configuration->Nios ii harware->new_configuration->target connection tab-> and select Ignore mismatched system ID" and "Ignore mismatched system timestamp.

New ContributorHi anand,
thanku for ur reply.
i had tried by ignoring the mismatched system id and timestap still not detecting any target connection.please help...
Regular ContributorHi,
Maybe .sof file not loaded or tool, before concluding
Can you try using the example project?

New Contributorthanku for u reply.
yes we followed example project and .sof file was loaded. I verified this by writing vhdl code (GPIO toggle with input clk 24mhz) in portmap file(top level entity) and compiled and loaded .sof file in FPGA it shows 100%. please help..
Regular ContributorTry using different Quartus version.
Have you used example project???
New Contributorplease tell me quartus versions which supports cyclone iii family
New Contributorthanku for ur reply.
i followed tutorials (introduction to qsys,my first nios tutorial etc.) Can u give any sample example project for cyclone iii which supports quartus 13.1?
please help..
Regular ContributorCheck below link
https://fpgacloud.intel.com/devstore/platform/?acds_version=13.1&family=cyclone-iii
Are you using dev kit or custom board?
New Contributorcustom board
Regular ContributorOkay,
Can you confirm if your usb blaster and usb cable are working fine with help of some other board??
If USB blaster are working fine. than problem is related to the power.
Check VCCINT, VCCIO, and VCCA pins if it is meeting it's POR requirements.
Also check the pull up / pull down resistors on configuration sides.

New Contributorthank u for ur reply.
i thought that .sof file was loaded 100% into fpga board means that USB Blaster -ii emulator works fine.
New Contributorand also the USB Blater ii emulator supports our fpga cyclone iii(EP3C80U484I7)?
Regular ContributorRecreate the eclipse project with correct sopcinfo and check.
New Contributorthanku for ur reply.
finally after doing above posibility iam going to install low ver Quartus ii (ver 12.1) with usb blaster ii emulator.
