AMBA5 CHI Verification IP provides an smart way to verify the ARM AMBA5 CHI component of a SOC or a ASIC. The SmartDV's AMBA5 CHI Verification IP is fully compliant with standard AMBA5 CHI Specification and provides the following features.
AMBA5 CHI VIP is supported natively in Verilog and VHDL
- Features
-
- Compliant with the latest ARM AMBA5 CHI specification.
- Supports CHI5 Master, Slave, Interconnect, Monitor and Checker.
- Support for Protocol, Network and Link layer communication, including flow control mechanisms across RN2HN and HN2SN links.
- Supports all CHI protocol node types:
- Request Nodes (RN-F, RN-D and RN-I)
- Home Nodes (HN-F, HN-I and MN)
- Slave Nodes (SN-F and SN-I)
- Supports Link initialization as per specs.
- Support for skipping link initialization and retrying failed link initialization.
- Configurable credit including dynamic and pre-allocated credit control.
- Cache model support in Master and Interconnect (programmable). Monitor has backdoor access to these cache models.
- Support for Speculative read and Snoop filtering.
- Support for all Transaction types/Opcodes including Barrier, DVM and Exclusive access.
- Supports all ARM AMBA5 CHI data widths.
- Support for Request transactions with/without a Retry and cancelling of transactions.
- Ability to issue multiple outstanding Non-snoopable/Snoopable transactions.
- Programmable Protocol flit delays and different channels delays. Interconnect has the ability to replicate RN/SN inserted delays.
- Supports all write/read responses and snoop responses.
- Fine grain control of below:
- Requester transaction including main memory access
- Completer response to a Requester transaction and Requester acknowledgment/response to Completer's response
- Interconnect generated snoop transaction to Snooped RNs
- Interconnect generated main memory access transactions.
- Snooped RN response to a snoop transaction.
- Supports fine grain control of response per address or per transaction.
- Device and Normal memory types support.
- Support for ordering of transactions/responses and reordering of data packets.
- Support for error injection during Link initialization.
- Ability to inject errors during transfers.
- Supports constrained randomization of protocol attributes.
- Programmable Timeout insertion.
- Supports FIFO memory.
- Rich set of configuration parameters to control CHI5 functionality.
- On-the-fly protocol and data checking including port level and system level checks.
- Notifies the testbench of significant events such as transactions, warnings, timing and protocol violations.
- Built in coverage analysis.
- Transaction logging and Performance Reporting support.
- Callbacks in Master, Slave, Interconnect and Monitor for various events.
- Status counters for various events on bus.
- AMBA5 CHI Verification IP comes with complete testsuite to test every feature of ARM AMBA5 CHI specification.
- Benefits
-
- Faster testbench development and more complete verification of AMBA5 CHI designs.
- Easy to use command interface simplifies testbench control and configuration of master and slave.
- Simplifies results analysis.
- Runs in every major simulation environment.
- AMBA5 CHI Verification Env
