| * | mem/extract_rdff: Add alternate transparency handling. | Marcelina Kościelnicka | 2021-05-25 | 1 | -18/+80 |
| | | | | | | | | | | | When extracting read register from a transparent port that has an enable, reset, or initial value, the usual trick of putting a register on the address instead of data doesn't work. In this case, create soft transparency logic instead. When transparency masks land, this will also be used to handle ports that are transparent to only a subset of write ports. | ||||
| * | opt_mem: Add reset/init value support. | Marcelina Kościelnicka | 2021-05-25 | 1 | -0/+12 |

| * | kernel/mem: Add model support for read port init value and resets. | Marcelina Kościelnicka | 2021-05-25 | 2 | -4/+73 |
| | | | | | | | | Like wide port support, this is still completely unusable, and support in various passes will be gradually added later. It also has no support at all in the cell library, so attempting to create a read port with a reset or initial value will cause an assert failure for now. | ||||

| * | Reject wide ports in some passes that will never support them. | Marcelina Kościelnicka | 2021-05-25 | 4 | -2/+35 |

| * | kernel/mem: Add a Mem::narrow helper to split up wide ports. | Marcelina Kościelnicka | 2021-05-25 | 2 | -0/+53 |

| * | kernel/mem: Emit support for wide ports in packed mode. | Marcelina Kościelnicka | 2021-05-25 | 1 | -30/+34 |
| | | | | | | | | Since the packed cell doesn't actually support wide ports yet, we just auto-narrow them on emit. The future packed cell will add RD_WIDE_CONTINUATION and WR_WIDE_CONTINUATION parameters so the transform will be trivially reversible for proper serialization. | ||||
| * | kernel/mem: Add model for wide ports. | Marcelina Kościelnicka | 2021-05-25 | 2 | -6/+28 |
| | | | | | | | Such ports cannot actually be created or used yet, this just adds the necessary plumbing in the helper. Subsequent commits will gradually add wide port support to various yosys passes. | ||||
| * | kernel/mem: Add priority_mask to model. | Marcelina Kościelnicka | 2021-05-25 | 2 | -1/+47 |
| | | | | | | | | | This is going to be used to store arbitrary priority masks in the future. Right now, it is not supported by our cell library, so the priority_mask is computed from port order on helper construction, and discarded when emitted. However, this allows us to already convert helper-using passes to the new model. | ||||
| * | opt_mem_feedback: Rewrite feedback path finding logic. | Marcelina Kościelnicka | 2021-05-24 | 3 | -115/+373 |

| * | memory_share: Split off feedback path finding as a separate pass. | Marcelina Kościelnicka | 2021-05-23 | 4 | -242/+343 |
| | | | | | | memory_share is actually three passes in a trenchcoat. Split off the one that has the least in common with the other two as a separate pass. | ||||

| | | | | | | | There will soon be more (versioned) memory cells, so handle passes that only care if a cell is memory-related by a simple helper call instead of a hardcoded list. | ||||

| * | Change the type of current_module to Module | Rupert Swarbrick | 2021-05-13 | 2 | -24/+26 |
| | | | | | | | | | | | | The current_module global is needed so that genRTLIL has somewhere to put cells and wires that it generates as it makes sense of expressions that it sees. However, that doesn't actually need to be an AstModule: the Module base class is enough. This patch should cause no functional change, but the point is that it's now possible to call genRTLIL with a module that isn't an AstModule as "current_module". This will be needed for 'bind' support. | ||||
| * | Use range-based for loop in AST::process | Rupert Swarbrick | 2021-05-13 | 1 | -21/+21 |
| | | | | | | | No functional change: just get rid of the explicit iterator and replace (*it)-> with child->. It's even the same number of characters, but is hopefully a little easier to read. | ||||
