-This component is a multi-channels, programmable, Hardware Interrupt  to Software Interrupt translator. It can be used to translate a variable number of hardware interrupt lines (HWI) to the same number of write triggered interrupt (SWI) that can be handled by a !VciXicu component. It acts as a VCI initiator, to send a single flit VCI packet to the target !VciXicu interrupt controller, when a rising/falling edge is detected on a given HWI input. It acts also as a memory mapped VCI target, as the addresses of the WTI associated to a given HWI must be configured by the software.

+It acts as a VCI initiator, to send a single flit VCI packet to the target !VciXicu interrupt controller, when a rising/falling edge is detected on a given HWI input. For each HWI channel, WTIs are periodically sent (each 5000 cycles) as long as the HWI input signal is high.

 It supports both 32 and 64 bits for the VCI data field width.
