//
// Description:
// This module manages multi-threaded transactions for one SI-slot.
// The module interface consists of a 1-slave to 1-master address channel, plus a
// (M+1)-master (from M MI-slots plus error handler) to 1-slave response channel.
// The module maintains transaction thread control registers that count the
// number of outstanding transations for each thread and the target MI-slot.
// On the address channel, the module decodes addresses to select among MI-slots
// accessible to the SI-slot where it is instantiated.
// It then qualifies whether each received transaction
// should be propagated as a request to the address channel arbiter.
// Transactions are blocked while there is any outstanding transaction to a
// different slave (MI-slot) for the requested ID thread (for deadlock avoidance).
// On the response channel, the module mulitplexes transfers from each of the
// MI-slots whenever a transfer targets the ID of an active thread,
// arbitrating between MI-slots if multiple threads respond concurrently.

//
// Description:
// This module manages multi-threaded transactions for one SI-slot.
// The module interface consists of a 1-slave to 1-master address channel, plus a
// (M+1)-master (from M MI-slots plus error handler) to 1-slave response channel.
// The module maintains transaction thread control registers that count the
// number of outstanding transations for each thread and the target MI-slot.
// On the address channel, the module decodes addresses to select among MI-slots
// accessible to the SI-slot where it is instantiated.
// It then qualifies whether each received transaction
// should be propagated as a request to the address channel arbiter.
// Transactions are blocked while there is any outstanding transaction to a
// different slave (MI-slot) for the requested ID thread (for deadlock avoidance).
// On the response channel, the module mulitplexes transfers from each of the
// MI-slots whenever a transfer targets the ID of an active thread,
// arbitrating between MI-slots if multiple threads respond concurrently.

// Description:
// This module manages multi-threaded transactions for one SI-slot.
// The module interface consists of a 1-slave to 1-master address channel, plus a
// (M+1)-master (from M MI-slots plus error handler) to 1-slave response channel.
// The module maintains transaction thread control registers that count the
// number of outstanding transations for each thread and the target MI-slot.
// On the address channel, the module decodes addresses to select among MI-slots
// accessible to the SI-slot where it is instantiated.
// It then qualifies whether each received transaction
// should be propagated as a request to the address channel arbiter.
// Transactions are blocked while there is any outstanding transaction to a
// different slave (MI-slot) for the requested ID thread (for deadlock avoidance).
// On the response channel, the module mulitplexes transfers from each of the
// MI-slots whenever a transfer targets the ID of an active thread,
// arbitrating between MI-slots if multiple threads respond concurrently.
