From 550310e2647c7aac1e49b79d9ff912436103062f Mon Sep 17 00:00:00 2001 From: whitequark Date: Wed, 1 Jan 2020 12:30:00 +0000 Subject: Harmonize BRAM/LUTRAM descriptions across all of Yosys. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit: * renames all remaining instances of "DRAM" (which is ambiguous) to "LUTRAM" (which is not), finishing the work started in the commit 698ab9be; * renames memory rule files to brams.txt/lutrams.txt; * adds/renames script labels map_bram/map_lutram; * extracts where necessary script labels map_ffram and map_gates; * adds where necessary options -nobram/-nolutram. The end result is that BRAM/LUTRAM/FFRAM aspects of every target are now consistent with each other. Per architecture: * anlogic: rename drams.txt→lutrams.txt, add -nolutram, add :map_lutram, :map_ffram, :map_gates * ecp5: rename bram.txt→brams.txt, lutram.txt→lutrams.txt * efinix: rename bram.txt→brams.txt, add -nobram, add :map_ffram, :map_gates * gowin: rename bram.txt→brams.txt, dram.txt→lutrams.txt, rename -nodram→-nolutram (-nodram still recognized), rename :bram→:map_bram, :dram→:map_lutram, add :map_ffram, :map_gates --- techlibs/anlogic/lutrams_map.v | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) create mode 100644 techlibs/anlogic/lutrams_map.v (limited to 'techlibs/anlogic/lutrams_map.v') diff --git a/techlibs/anlogic/lutrams_map.v b/techlibs/anlogic/lutrams_map.v new file mode 100644 index 000000000..5a464cafc --- /dev/null +++ b/techlibs/anlogic/lutrams_map.v @@ -0,0 +1,22 @@ +module \$__ANLOGIC_DRAM16X4 (CLK1, A1ADDR, A1DATA, B1ADDR, B1DATA, B1EN); + parameter [63:0]INIT = 64'bx; + input CLK1; + + input [3:0] A1ADDR; + output [3:0] A1DATA; + + input [3:0] B1ADDR; + input [3:0] B1DATA; + input B1EN; + + EG_LOGIC_DRAM16X4 #( + `include "lutram_init_16x4.vh" + ) _TECHMAP_REPLACE_ ( + .di(B1DATA), + .waddr(B1ADDR), + .wclk(CLK1), + .we(B1EN), + .raddr(A1ADDR), + .do(A1DATA) + ); +endmodule -- cgit v1.2.3
