From b40c3d6cb20081ff8941fc4addef92170ffb01a9 Mon Sep 17 00:00:00 2001 From: GuzTech Date: Thu, 26 Nov 2020 15:50:00 +0100 Subject: [breaking-change] Add `_n` suffix to argument names of pins with fixed inverters. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Note: this change does NOT affect pin functionality or naming, and does not require modifying your design. It does however affect some board files, where keywords corresponding to active low pins will have to be adjusted: SPIResource(0, cs="C1", ...) → SPIResource(0, cs_n="C1", ...) The new naming scheme will make it easier to write and audit board files by clearly marking inverted pins in resource factories, similarly to how `PinsN` indicates the same in bare resources.
