v0.4.0

Added

• Added assertions to XY routers with routing optimization enabled to catch packets that want to Y->X which is illegal in XY routing.

Changed

• The parameters EnMgrPort and EnSbrPort are swapped in the chimneys to be more consistent. FlooNoC defines subordinate ports as requests that go out of the NoC to AXI subordinates (i.e. memories) that return a response, and manager ports as requests that come into the NoC from AXI managers (i.e. cores).
• The floo_narrow_wide_join now uses axi_riscv_atomics to filter out atomic operations. The atop_filter are still there but are disabled by default.

Fixed

• Synthesis wrappers now use the more generic id_t instead of the deprecated xy_id_t type as a parameter.
• The specified ID offset is now also rendered for routers in floogen.
• Fixed a template rendering issue where XY routers could not be rendered when the first direction (EJECT) was not defined.

Removed

• Removed floo_synth_mesh, floo_synth_mesh_ruche & floo_synth_router_simple synthesis wrappers, since they are not used anymore.
