AMBA ACE4 Synthesizable Transactor provides a smart way to verify the ARM AMBA ACE4 component of a SOC or a ASIC in Emulator or FPGA platform. The SmartDV's AMBA ACE4 Synthesizable Transactor is fully compliant with standard AMBA ACE4 Specification and provides the following features
- Features
-
- Compliant with the latest ARM AMBA ACE4 Protocol Specification.
- Supports ACE4 Master and Slave.
- Supports all ACE4 data and address widths.
- Supports all protocol transfer types, burst types, burst lengths, burst sizes and response types.
- Supports constrained randomization of protocol attributes.
- Separate address, data and response phases. Separate read, write and snoop channels.
- Support for burst-based transactions with only start address issued.
- Slave and Master support fine grain control of response per address or per transaction.
- Programmable wait states or delay insertion on different channels.
- Ability to inject errors during data transfer.
- Write strobe support to enable sparse data transfer on the write data bus.
- Narrow transfer support.
- Unaligned address access support.
- Ability to issue multiple outstanding transactions.
- Out of order transaction completion support.
- Protected accesses with normal/privileged, secure/non-secure and data/instruction
- Ability to configure the width of all signals.
- Support for bus inactivity detection and timeout(configuration parameter and dynamic change of inactivity timer).
- Configurable WID signal enable support.
- Read data interleaving support with programmable interleave depth and programmable interleave size per transaction to allow fixed and variable data interleaving in a transaction.
- Atomic access support with normal access and exclusive access
- Longer bursts up to 256 beats.
- Quality of Service signaling.
- Multiple region interfaces.
- User signaling support.
- Ability to break longer bursts into multiple shorter bursts
