Undocumented switchblock_location type

[AmirhosseinPoolad]

The architecture in vtr_flow/arch/custom_sb_location/stratixiv_arch.timing.xml uses a switchblock_location tag with type="XY_SPECIFIED" which is undocumented. This option was added in #2664 .

This should either be fixed by @saaramahmoudi or (if you know what to write) you could fix it @AmirhosseinPoolad .

@AmirhosseinPoolad tells me he isn't entirely sure of the option functionality, so if you can document this it would be best @saaramahmoudi .

[saaramahmoudi]

That is okay; I will document this by next week if that is not late. @vaughnbetz

Thanks @saaramahmoudi ; not too late at all.
