Detailed Description
State relating to routing.
This should contain only data structures that describe the current routing implementation, or related router algorithmic state.
Field Documentation
◆ cached_router_lookahead_
| vtr::Cache<std::tuple<e_router_lookahead, std::string, std::vector<t_segment_inf> >, RouterLookahead> RoutingContext::cached_router_lookahead_ |
Cache of router lookahead object.
Cache key: (lookahead type, read lookahead (if any), segment definitions).
◆ clb_opins_used_locally
| t_clb_opins_used RoutingContext::clb_opins_used_locally |
◆ is_clock_net
| vtr::vector<ClusterNetId, uint8_t> RoutingContext::is_clock_net |
◆ net_rr_terminals
| vtr::vector<ClusterNetId, std::vector<int> > RoutingContext::net_rr_terminals |
◆ net_status
| t_net_routing_status RoutingContext::net_status |
Information about current routing status of each net.
◆ non_configurable_bitset
| vtr::dynamic_bitset RoutingContext::non_configurable_bitset |
Information about whether a node is part of a non-configurable set.
(i.e. connected to others with non-configurable edges like metal shorts that can't be disabled) Stored in a single bit per rr_node for efficiency bit value 0: node is not part of a non-configurable set bit value 1: node is part of a non-configurable set Initialized once when RoutingContext is initialized, static throughout invocation of router
◆ route_bb
| vtr::vector<ClusterNetId, t_bb> RoutingContext::route_bb |
Limits area within which each net must be routed.
◆ routing_id
| std::string RoutingContext::routing_id |
SHA256 digest of the .route file.
Used for unique identification and consistency checking
◆ rr_blk_source
| vtr::vector<ClusterBlockId, std::vector<int> > RoutingContext::rr_blk_source |
◆ rr_node_route_inf
| std::vector<t_rr_node_route_inf> RoutingContext::rr_node_route_inf |
◆ trace
| vtr::vector<ClusterNetId, t_traceback> RoutingContext::trace |
◆ trace_nodes
| vtr::vector<ClusterNetId, std::unordered_set<int> > RoutingContext::trace_nodes |
