06:36 <jer_emy[m]> I'm struggling a little with the latest version of amaranth. This code used to work fine: `platform.request('clk16', dir='i')`, but now I get `TypeError: Object flipped((rec clk16_0 i)) cannot be converted to an Amaranth value`

06:36 <jer_emy[m]> can anyone point me to what I am doing wrong ?

06:55 <miek__[m]> you need to use the i attribute of the resource to get at the value, ie: platform.request(...).i

07:01 <jer_emy[m]> thank you!

15:55 <mcc111[m]> Hey, a little off topic but I have a Quartus/IDE related question... (full message at <https://catircservices.org/_matrix/media/v3/download/catircservices.org/UvmrcZBpYGnRjRUcsToTmoPg>)

16:06 <ravenslofty[m]> ...it's true that SDC is just Tcl, but when interpreting SDC tooling doesn't really expect to do I/O

16:15 <mcc111[m]> That makes sense, but also if we think of SDC as a file format used in compilation rather than "a programming language", one of the core functions of interpreting user code is to report warnings and errors, and most programming-related formats have some means for injecting a message into the error stream, such as "#error"

16:15 <mcc111[m]> Are you saying you believe this just doesn't happen to exist in the SDC context?

16:17 <mcc111[m]> Do you think, if I do normal tcl file ops such as "open"/"close", this will be specifically suppressed by the environment?

16:35 <mcc111[m]> hmm, open/close do work! cool

16:47 <whitequark[cis]> note that XDC is not Tcl

16:48 <whitequark[cis]> (the Xilinx variant)

16:50 <mcc111[m]> that's good to know

16:51 <ravenslofty[m]> (and `nextpnr-mistral` does not evaluate `.qsf` files as Tcl even though they "should" be)

18:26 <mcc111[m]> I printed the value of `[get_ports clk_74a]` and it turned out to be "_col0"... (full message at <https://catircservices.org/_matrix/media/v3/download/catircservices.org/JfMiWlYSnaAzHnrRjyKiuNmF>)
