From ab63d78a6ce60854474c31e47ce8c27993e977fa Mon Sep 17 00:00:00 2001 From: Wade Fife Date: Sat, 7 Jan 2023 19:24:26 -0600 Subject: [PATCH] fpga: Add BUILD_SEED variable Adds a BUILD_SEED make variable that can be set to a 32-bit integer, and adds an FPGA read-only register initialized by this variable. Changing this variable will randomly affect the FPGA build results. This can be useful when your build fails timing by a small amount, allowing you to build again and get different results with the same code. For example, you could run the following to produce an FPGA build with different timing results from the default build: make X310_XG BUILD_SEED=123 Original-commit: 3a3a03486f9221c2e59fa6d0826c23d17730956d --- top/e31x/Makefile | 25 +++-- top/e31x/e31x_core.v | 10 +- top/e320/Makefile | 18 ++-- top/e320/e320_core.v | 15 ++- top/n3xx/Makefile | 28 +++--- top/n3xx/n3xx_core.v | 15 ++- top/x300/Makefile | 22 +++-- top/x300/bus_int.v | 10 +- top/x400/Makefile | 15 ++- top/x400/doc/X4XX_FPGA_left.htm | 1 + top/x400/doc/X4XX_FPGA_right.htm | 93 ++++++++++++++++++- top/x400/regmap/global_regs_regmap_utils.vh | 8 +- .../regmap/versioning_regs_regmap_utils.vh | 4 +- top/x400/x4xx.v | 4 +- top/x400/x4xx_global_regs.v | 14 +++ 15 files changed, 221 insertions(+), 61 deletions(-) diff --git a/top/e31x/Makefile b/top/e31x/Makefile index f4e744b..45b8dae 100644 --- a/top/e31x/Makefile +++ b/top/e31x/Makefile @@ -14,6 +14,10 @@ ## build/usrp__fpga_.dts: Device tree source file ## build/usrp__fpga_.rpt: Build report (includes utilization and timing summary) +# Initialize a build seed.
