# Accelerated VIP for AXI4 Protocol

The idea of using Accelerated VIP is to push the synthesizable part of the testbench into the separate top module along with the interface and it is named as HDL TOP and the unsynthesizable part is pushed into the HVL TOP. This setup provides the ability to run the longer tests quickly. This particular testbench can be used for the simulation as well as the emulation based on mode of operation.


# Features:
1. Support read and write Independent channels
2. Separate address/control and data phases
3. Blocking and Non Blocking Transfers
4. Parallel write and read transfer
5. Support outstanding transfer
6. No strict timing relationship between address and data operations
7. Support different types of Burst based transactions (fixed, incr, wrap)
8. Support okay and slave error response
9. Support for Out-of-order transaction
10. Support for Quality of service(QOS)
11. Support for Unaligned address transfers
12. Support for Custom Slave memory 
13. Support for Narrow transfers
