VIP for AXI Protocol

AXI

VIP for AXI Protocol

Architecture

Components

1. Sequence item
2. Sequence - 2 sequence were made as in AXI read and write can happen in parallel.
3. Sequencer - 2 Sequencer were connected to a single driver so that the read and write operation are independent of each other and can happen in parallel
4. Driver - One each in master and slave
5. Monitor - One each in master and slave
6. Scoreboard
7. Environment
8. Test - Comprises of one base test, and 5 directed test cases.
9. TestBench top - Environment can be configured from here
10. Configuration Object:
    • env_config - Config object to configure the environment and agents
    • test_config - Config object to configure the test.

How to use

• Download the latest release from below or visit the release page for more old release.
• Copy the contents in a folder.
• Compile tb_top.sv in any simulator and simulate top module.
• Different test classes can be selected using +UVM_TESTNAME directive.

axi's Issues

axi slave hanging

Hi
I am adopting an axi slave as a memory in our environment, but it didn't exist and was hanging when test cases finished.

Sequence Item

Development of AXI transaction packet which will hold all the respective data that needs to be sent to the master.

how to run on EDAPlayground?

Kindly let me know how to run on edaplayground!

Interface implementation

Assertions should be added

Config DB objects

RDATA does not return from axi_m_driver

Hello. Why are you choose the Sequence-Driver API "get_next_item() followed by item_done()" ?
Don't you think would it be better to use "get(req) followed by put(rsp)" model (this naming I get from UVM cookbook)?
With "get(req) followed by put(rsp)" model you can return to sequence read data and bresp status.

Strobe signal addition

Add the support for the strobe signal in various channels of axi

Hello,

How can I run this on EDA playground?

Slave

Following things need to be implemented

• Driver - Will drive the slave signals
• Monitor - Will monitor the interface.

Scoreboard

Implementation of scoreboard

Plan development roadmap

Plan out the following things:

• 1. Functionalities to be included in each release
• 2. TB architecture development
• 3. Feature Extraction
• 4. Coverage descriptions

Master

Master will have following components:

• Write Sequencer
• Read Sequencer
• Driver
• Monitor

Both sequencers will run parallelly to create read and write simultaneously, as AXI has dedicated read and write channel

Sequence

2 base sequences to be implemented:

• Write Sequence - Will generate write transaction packets
• Read Sequence - Will generate read transaction packets
