{
Improved UpdateSession & exception catching. Start of RoutingGauge implem. Miscellaneous: * Change: In <crlcore>, in display.conf use the same display threshold for both METAL2 & METAL3. In alliance.conf, the side of VIAs in the gauge is 2l (not 3l). In kite.conf, separate edge densities for H/V. * Change: In <Cell>, in flattenNets() use flag as argument, not a boolean. Do not create rings for clock or supply nets. * Change: In <DeepNet>, in _createRoutingPads() do not create rings for clock or supply net (duplicated policy as in Cell::flattenNets()). * Bug: In <ControllerWidget>, at last find the bad signal disconnect that was causing ungraceful messages. * Change: In <knik>, in Edge display occupancy/capacity in the string name. Improved display progress and debugging capabilities. Improved exception catch & breakpoint managment: * Bug: In <PaletteWidget>, in updateExtensions() replace the calls to deleteLayer() by delete. This cause the widget to be immediatly erased instead of waiting for the event queue to be completly processed. This was causing the widget to be left in a incoherent state when stoping at a breakpoint. * Bug: In <BreakpointWidget>, in execNoModal(), flush the main event loop (QApplication::flush()) *before* lauching the *local* event loop. This is to ensure all widgets are in their final state when waiting (especially <PaletteWidget>). * Change: In <ExceptionWidget>, new method catchAllWrapper() to execute any std::function< void() > function/method with a "try"/ "catch" wraparound and lauch the widget in case something is catch. * New: In <hurricane>, support for a oberver pattern, backported from <katabatic> with an Obervable capable of being linked to any number of Obervers. * New: In <Cell>, made it observable to detect Cell change, currently emit two kind of signals: - Cell::CellAboutToChange : *before* any change. - Cell::CellChanged : *after* the change has been completed. * New: In <UpdateSession>, in Go::invalidate() add the Cell owning the Go to the UPDATOR_STACK (of course the cell is added only once). In addition, when the Cell is added, send a notification of Cell::CellAboutToChange to all it's observers. The slave instances are also invalidated. Conversely in UpdateSession::_preDestroy() for each invalidated Cell send a Cell::CellChanged notification to all observer. The UPDATOR_STACK has been slightly amended to accept Cell which are not Gos. Prior to this, the Cell where completly excluded from the UpdateSession mechanism, so it's instances where never actualised of anything referring to the Cell for that matter. Note: we use two different mechanisms to transmit a Cell change, observers and the slave instance map. I think at some point it should be unificated. * Change: In <CellViewer>, make it a Cell observer to redraw when the cell is modificated (also update the palette). Uses the catchAllWrapper() to protect all critical actions. * Change: In <GraphicTool>, no longer need of cellPreModificated and cellPostModificated signals. Now done through the Cell obersvers. * Change: In <mauka>, <etesian> & <kite> now uses the catchAllWrapper method for protection (need to split methods in two, to be able to pass it as argument). No longer emit cellPreModificated and cellPostModificated. Support for RoutingGauge in P&R: * Bug: In <placeandroute.py>, the connection from the internal power ring to the connectors was not done correctly. Wrong contact layers leading to a gap. * Change: In <BuildPowerRails>, detection of the corona signals based on how the "pck_px" pad is connected. No longer based on name matching. * Change: In <placeandroute.py>, support for 2 routing metal only (3 metal in the technology). * Change: In <katabatic> & <kite> support for a "top layer" limitation on the routing gauge, this allows to use only two routing metals (METAL2 & METAL3). Work in progress.

Implementation of pre-routing support (for clock-tree compliance). * New: In Katabatic, in <AutoContact>, this class is no longer derived from ExtentionGo. With the simplificated AutoContacts, there is no reason to do so, and it will save some QuadTree insertions/deletions. New factory function AutoContact::createFrom(Contact*) which try to build an AutoContact on top of a Hurricane::Contact. Of course that base contact *must fit* into one of the predefined Contact configurations (Terminal, Turn, HTee or VTee). NOTE: This implies that the pre-routed segments & contacts *are* correctly articulated, which is not the case when a Cell is read from disk in "ap" format. The pre-routing feature must be used for now without any re-read from disk. We will implement a re-articulating pre-process in the future. * Change: In Katabatic, in <AutoContact> derived classes, the ::updateCache() method now display an accurate error message if a segment is connected but has no AutoSegment conterpart (i.e. the lookup fails). * New: In Katabatic, in <AutoSegment>, the ::computeOptimal() method is short-circuited for pre-routed segments, the optimal axis position is considered to be the one it is currently on (i.e. we trust the designer). * New: In Katabatic, in <KatabaticEngine>, the ::loadGlobalRouting() method now accept a map of excluded nets (same as Knik). This map is the one of pre-routed nets. * New: In Katabatic, in layer assignment, do not try to displace fixed segments... * New: In Katabatic, in <AutoSegment>, new flag SegUserDefined and related methods to know if a segment comes from the global router (Knik) or is pre-routed (supplied by the user). * New: In Kite, In <BuildPowerRails>, support (exclusion) for pre-routed nets. * New: In Kite, In <GraphicKiteEngine> new menu entry for running the router on pre-routed nets ("Detailed Pre-Route"), also integrated in the all-on-one route command. * New: In Kite, In KiteEngine, new method ::_initDataBase() that group all the initialisation steps. It is a mix of calls between Knik and Kite initializations which are intertwinneds (may have to devellop a shared common base at a later point). It creates the Knik grid, then the Katabatic grid, then load pre-routed wires and power rails and protect isolated RoutingPads. Add support for a map of pre-routed nets (to be excluded for Knik calls). The method "::run()" now uses function flags, firstly to know if it is managing pre-routed wires or general purposes ones. * New: In Kite, in <NegociateWindow>, the "::run()" methods has now two modes. The normal one and the 'KtPreRoutedStage' that is for routing pre-routed nets. When in pre-route stage, the wires are fixed at the end of this step. * New: In Kite, in <TrackElement> add decorator for AutoSegment isUsedDefined(). * New: In Kite, in <TrackSegment>, the various ::canDogleg() methods returns false for a pre-routed (user-defined segment). * New: In Kite, in PyKiteEngine, added new method runNegociatePreRouted().

Improved UpdateSession & exception catching. Start of RoutingGauge implem. Miscellaneous: * Change: In <crlcore>, in display.conf use the same display threshold for both METAL2 & METAL3. In alliance.conf, the side of VIAs in the gauge is 2l (not 3l). In kite.conf, separate edge densities for H/V. * Change: In <Cell>, in flattenNets() use flag as argument, not a boolean. Do not create rings for clock or supply nets. * Change: In <DeepNet>, in _createRoutingPads() do not create rings for clock or supply net (duplicated policy as in Cell::flattenNets()). * Bug: In <ControllerWidget>, at last find the bad signal disconnect that was causing ungraceful messages. * Change: In <knik>, in Edge display occupancy/capacity in the string name. Improved display progress and debugging capabilities. Improved exception catch & breakpoint managment: * Bug: In <PaletteWidget>, in updateExtensions() replace the calls to deleteLayer() by delete. This cause the widget to be immediatly erased instead of waiting for the event queue to be completly processed. This was causing the widget to be left in a incoherent state when stoping at a breakpoint. * Bug: In <BreakpointWidget>, in execNoModal(), flush the main event loop (QApplication::flush()) *before* lauching the *local* event loop. This is to ensure all widgets are in their final state when waiting (especially <PaletteWidget>). * Change: In <ExceptionWidget>, new method catchAllWrapper() to execute any std::function< void() > function/method with a "try"/ "catch" wraparound and lauch the widget in case something is catch. * New: In <hurricane>, support for a oberver pattern, backported from <katabatic> with an Obervable capable of being linked to any number of Obervers. * New: In <Cell>, made it observable to detect Cell change, currently emit two kind of signals: - Cell::CellAboutToChange : *before* any change. - Cell::CellChanged : *after* the change has been completed. * New: In <UpdateSession>, in Go::invalidate() add the Cell owning the Go to the UPDATOR_STACK (of course the cell is added only once). In addition, when the Cell is added, send a notification of Cell::CellAboutToChange to all it's observers. The slave instances are also invalidated. Conversely in UpdateSession::_preDestroy() for each invalidated Cell send a Cell::CellChanged notification to all observer. The UPDATOR_STACK has been slightly amended to accept Cell which are not Gos. Prior to this, the Cell where completly excluded from the UpdateSession mechanism, so it's instances where never actualised of anything referring to the Cell for that matter. Note: we use two different mechanisms to transmit a Cell change, observers and the slave instance map. I think at some point it should be unificated. * Change: In <CellViewer>, make it a Cell observer to redraw when the cell is modificated (also update the palette). Uses the catchAllWrapper() to protect all critical actions. * Change: In <GraphicTool>, no longer need of cellPreModificated and cellPostModificated signals. Now done through the Cell obersvers. * Change: In <mauka>, <etesian> & <kite> now uses the catchAllWrapper method for protection (need to split methods in two, to be able to pass it as argument). No longer emit cellPreModificated and cellPostModificated. Support for RoutingGauge in P&R: * Bug: In <placeandroute.py>, the connection from the internal power ring to the connectors was not done correctly. Wrong contact layers leading to a gap. * Change: In <BuildPowerRails>, detection of the corona signals based on how the "pck_px" pad is connected. No longer based on name matching. * Change: In <placeandroute.py>, support for 2 routing metal only (3 metal in the technology). * Change: In <katabatic> & <kite> support for a "top layer" limitation on the routing gauge, this allows to use only two routing metals (METAL2 & METAL3). Work in progress.
