// The Elastic Silicon Interconnect (ESI) dialect
//
// ESI is a system interconnect generator. It is type safe and
// latency-insensitive. It can be used for on-chip, inter-chip, and host-chip
// communication. It is also intended to help with incremental adoption and
// integration with existing RTL as it provides a standardized, typed interface
// to the outside world.
