SBB tile design and integration: 

• MR !486: This merge request focuses on the finalization of design, characterization and model extraction of the sbb_tile, as well as adapting uvm tests 
• MR !631  This MR adapts periphery and sbb_tile_wrapper instance for the new sbb_tile and adapts the implementation flow.

      Above MRs to be merged today, and follow up in: 

• libery characterization:  #809
• timing closure: #828

Estimates: #809 to be closed by the end of Thursday 11/07,  #828  - more detailed stufy done by the end of the week 12/07, and not urgent sub-issued to be followed-later. 

With closing these 2 issues, sbb_tile will be fully integrated leaving several other followup issue for QoR imporvement. 

SBB tile integration inside the periphery:

• liberate trials : !677 (closed)

Notes:

Work in !486 done on 6M2Y, (re)porting of MOSAIX_sbb_bridges/sbb_tile to 7ML1F be done today by Corentin

Periphery implementation flow:

• power domain configuration (pd_gd) for sbb_tile and added isolation cells !388 (merged)
• added report lint !551 (merged)
• power strips out of pitch to the pixel matrix !594 (merged)
• adding power pin on periphery for new conf bit !537 (merged)

• timing reports differ significantly from design_finishing and export (design_finishing.sta) !584 (WIP) 

  Note: Other issues for periphery implementation: 
  • • Several other open issues for the periphery flow, not critical. This work to start after solving timing and lib issues for sbb_tile
      • followpin wires missing #730
      • #492, GDomain nets rebuffered in the LDomain #491, metall fill verification #446
      • enable non default rules #447
