* | ice40: Add ice40_braminit pass to allow initialization of BRAM from file | Sylvain Munaut | 2019-03-08 | 1 | -37/+51 |
| | | | | | | | | This adds a INIT_FILE attribute to the SB_RAM40_4K blocks that will initialize content from a hex file. Same behavior is imlemented in the simulation model and in a new pass for actual synthesis Signed-off-by: Sylvain Munaut <tnt@246tNt.com> | ||||

* | Merge pull request #724 from whitequark/equiv_opt | Clifford Wolf | 2018-12-16 | 1 | -0/+2 |
|\ | | | | | equiv_opt: new command, for verifying optimization passes | ||||
| * | equiv_opt: pass -D EQUIV when techmapping. | whitequark | 2018-12-07 | 1 | -0/+2 |
| | | | | | | | | | | This allows avoiding techmap crashes e.g. because of large memories in white-box cell models. | ||||
* | | Only use non-blocking assignments of SB_RAM40_4K for yosys | Olof Kindgren | 2018-12-06 | 1 | -0/+19 |
|/ | | | | | | | | | | | In an initial statement, blocking assignments are normally used and e.g. verilator throws a warning if non-blocking ones are used. Yosys cannot however properly resolve the interdependencies if blocking assignments are used in the initialization of SB_RAM_40_4K and thus this has been used. This patch will change to use non-blocking assignments only for yosys | ||||

* | Avoid mixing module port declaration styles in ice40 cells_sim.v | Olof Kindgren | 2018-05-17 | 1 | -43/+23 |
| | | | | | | The current code requires workarounds for several simulators For modelsim, the file must be compiled with -mixedansiports and xsim needs --relax. | ||||
