| * | Harmonize BRAM/LUTRAM descriptions across all of Yosys. | whitequark | 2020-01-01 | 1 | -16/+0 |
| | | | | | | | | | | | | | | | | | | | | | | | | | 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 | ||||
| * | anlogic: implement DRAM initialization | Icenowy Zheng | 2018-12-20 | 1 | -1/+1 |
| | | | | | | | | | | | | As the TD tool doesn't accept the DRAM cell to contain unknown values in the initial value, the initialzation support of DRAM is previously skipped. Now add the support by add a new pass to determine unknown values in the initial value. Signed-off-by: Icenowy Zheng <icenowy@aosc.io> | ||||
| * | anlogic: fix dbits of Anlogic Eagle DRAM16X4 | Icenowy Zheng | 2018-12-18 | 1 | -1/+1 |
| | | | | | | | | | | The dbits of DRAM16X4 is wrong set to 2, which leads to waste of DRAM bits. Fix the dbits number in the RAM configuration. Signed-off-by: Icenowy Zheng <icenowy@aosc.io> | ||||
| * | anlogic: add support for Eagle Distributed RAM | Icenowy Zheng | 2018-12-17 | 1 | -0/+16 |
| The MSLICEs on the Eagle series of FPGA can be configured as Distributed RAM. Enable to synthesis to DRAM. As the Anlogic software suite doesn't support any 'bx to exist in the initializtion data of DRAM, do not enable the initialization support of the inferred DRAM.
