Honored ContributorI'm looking for a recent design for the cyclone iii fpga development board using a Nios2 with MMU and the TSE.
I am using QII 10.1sp1 and SOPC Builder. Are there some as 'reference design' ? TIA, Fred
Honored ContributorFinally, I found one here (http://www.alterawiki.com/uploads/f/f6/20110211_nios2_linux_3c120_125mhz_10.1sp1.tgz).
However, I can't compile it, using QII v10.1sp1, without a 'Timing requirements not met'...Honored ContributorCheck what timing requirements it fails... Possibly JTAG or something not very serious.
Honored ContributorThe Worst case Timing Paths indicates a slack=-0.033 for the Slow 1200mV 85C Model Setup of the ddr2_Lo_xxx|altpll_component|...pll1|clk[1].
I don't know if there is a relationship, but the verification fails after a nios2-download of my kernel...Honored ContributorAnd the same problem is reported also in the Worst-case slack section of "Multicorner Timing analysis Summary".
Honored ContributorFinally, my kernel boots, it was a bad software configuration. It hangs a little bit later, but that's normal life for a first try!
I hope/suppose the Timing error is not too serious...
