17:28 <Wanda[cis]> so I have a device (XPLA3 CPLD) with a cursed JTAG interface

17:29 <Wanda[cis]> according to ISE SVF the erase/programming sequence involves having to go to IR-Pause for a specific amount of cycles at some points

17:29 <Wanda[cis]> the SVF also contains manually specified state transitions, which are currently unsupported by the glasgow applet

17:30 <Wanda[cis]> and the TAPInterface class doesn't support direct enough control either

17:33 <Wanda[cis]> so... I suppose I'm going to try extending the jtag-svf applet at least enough to deal with the specific cursed state transitions involved, and extending the TAPInterface to allow ending the shift in pause-states and spending a set amount of cycles in those?

17:33 <Wanda[cis]> not quite sure how to go about it

17:34 <Wanda[cis]> the specific sequences involved are:... (full message at <https://catircservices.org/_matrix/media/v3/download/catircservices.org/wzUZFbmKFyCSmDoZqgwvNtUI>)

17:35 <Wanda[cis]> specifically I want to write a program-xpla3 applet to program these cursed things

17:36 <Wanda[cis]> so I want the TAPInterface extension mostly; SVF stuff is of less interest

22:41 <whitequark[cis]> extending irpause/drpause sounds good to me (that was simply never needed before)

22:41 <whitequark[cis]> less sure about manual state transitions

22:42 <whitequark[cis]> are those specifying the non shortest ones?
