From ca0fd665dcf6a4aeda07955d3898b03204c88fd8 Mon Sep 17 00:00:00 2001 From: Wendy Elsasser Date: Tue, 14 Feb 2017 15:09:18 -0600 Subject: mem: Update DRAM configuration names Names of DRAM configurations were updated to reflect both the channel and device data width. Previous naming format was: __ The following nomenclature is now used: __x where n = The number of devices per rank on the channel x = Device width Total channel width can be calculated by n*w Example: A 64-bit DDR4, 2400 channel consisting of 4-bit devices: n = 16 w = 4 The resulting configuration name is: DDR4_2400_16x4 Updated scripts to match new naming convention. Added unique configurations for DDR4 for: 1) 16x4 2) 8x8 3) 4x16 Change-Id: Ibd7f763b7248835c624309143cb9fc29d56a69d1 Reviewed-by: Radhika Jagtap Reviewed-by: Curtis Dunham --- configs/dram/lat_mem_rd.py | 2 +- configs/dram/sweep.py | 4 ++-- 2 files changed, 3 insertions(+), 3 deletions(-) (limited to 'configs/dram') diff --git a/configs/dram/lat_mem_rd.py b/configs/dram/lat_mem_rd.py index f148656f2..ddc44e229 100644 --- a/configs/dram/lat_mem_rd.py +++ b/configs/dram/lat_mem_rd.py @@ -80,7 +80,7 @@ except: parser = optparse.OptionParser() -parser.add_option("--mem-type", type="choice", default="DDR3_1600_x64", +parser.add_option("--mem-type", type="choice", default="DDR3_1600_8x8", choices=MemConfig.mem_names(), help = "type of memory to use") parser.add_option("--mem-size", action="store", type="string", diff --git a/configs/dram/sweep.py b/configs/dram/sweep.py index ac232a8fd..32cf00345 100644 --- a/configs/dram/sweep.py +++ b/configs/dram/sweep.py @@ -53,8 +53,8 @@ from common import MemConfig parser = optparse.OptionParser() -# Use a single-channel DDR3-1600 x64 by default -parser.add_option("--mem-type", type="choice", default="DDR3_1600_x64", +# Use a single-channel DDR3-1600 x64 (8x8 topology) by default +parser.add_option("--mem-type", type="choice", default="DDR3_1600_8x8", choices=MemConfig.mem_names(), help = "type of memory to use") -- cgit v1.2.3
