Altera MAX-II: User logic access to USERCODE_REGISTER?

google: "cyclone bscan" - to find what I antti (me) have written about this

MAXII is similar to Cyclone, I have verified that in silicon

Thanks!

BTW, is there a way to make quartus_pgm play SVF files (or convert SVF into some other format I can play)? I would like to play the following file:

SIR 10 TDI (007); SDR 32 TDI (FFFFFFFF); ! or some other pattern

I would then expect to observe the USERCODE value being shifted out of the maxii_jtag module from my user logic.

you can defenetly use jam/stapl with quartus, its a bit pain as it requres CRC I think it can be ignored and after warning quartus programmer will accept the file but its generically more pain than using SVF

you can connect Cable III to the JTAG and use impact, or I could search my hard disk and upload a XSVFplayer that supports byteblaster cable

Is there a way to convert SVF to JAM/STAPL using Qaurtus? I was hoping I could just do something like

quartus_pgm --play-svf file.svf

or similar.

I'll just make a jumper and use the JTAG Techologies BV software... Thanks.

Can you play SVF files with impact? How?

Thank you for your help.

yes you can play SVF files with impact, just add them :)

I guess you mean XSVF files?

I can't find out how to play XSVF files in batch mode, there is a play command but it does not seem to take a filename as an argument.

Petter

The solution was to use addDevice to add the file and then use play:

setMode -bscan setCable -port lpt1 addDevice -p 1 -part file.xsvf play quit
