0.1.24

Notable changes in this release:

• Fixed transfer length checks

0.1.22

Notable changes in this release:

• For FIXED burst type, issue all bursts with the same starting address
• Add transfer length checks to prevent reads/writes running over the end of the address space
• Add sparse memory model
• Update AXI memory models to use sparse memory
• Add SparseMemoryRegion object

0.1.20

Notable changes in this release:

• Explicit cast to integer when using enum and flag types
• Support interleaved read data in AXI master
• Change AXI stream model to use bytes by default even when tkeep is not connected to better align with the spec
• Pass though full address for unaligned operations in AXI and AXI lite master modules
• Various optimizations to improve simulation speed

0.1.18

Notable changes in this release:

• Cache clock edge events to improve performance
• Use start_soon instead of fork
• Make size optional when creating windows
• Support overriding allocation region and window types
• Make wstrb optional
• Call write from init_write via start_soon so command FIFO size can be limited

0.1.16

Notable changes in this release:

• Logging performance improvements
• Add attributes for address and ID width
• Add address range and data type checks
• Add address space abstraction
• Add AXI/AXI lite slave modules

0.1.14

Notable changes in this release:

• Fix active state tracking in AXI stream model
• Remove deprecated assignments

0.1.12

Notable changes in this release:

• Improve burst handling to validate burst length and sideband signals
• Implement tag manager to dynamically allocate per-tag processing elements to improve simulation performance
• Reduce copying in sources to improve simulation performance
• Renamed byte_width to byte_lanes
• Print connected signal information in log output
• Improve handling of optional signals
• Make resp and prot signals optional

0.1.10

Notable changes in this release:

• Remove get_write_resp and get_read_data in AXI models
• Return operation complete event from init_read and init_write in AXI models
• Limit channel queue depth in AXI models
• Use per-ID coroutines for handling AXI transfers in AXI master to support out-of-order operations
• Improve reset code - warn about dropped operations, trigger events to prevent deadlocks, track operations actively being processed
• Enforce max queue depth and throw QueueEmpty and QueueFull exceptions in non-blocking operations on streaming interfaces

0.1.8

Notable changes in this release:

• Use cocotb-bus due to deprecations in cocotb
• Use cocotb async queues

0.1.6

Notable changes in this release:

• Added AxiBus, etc. objects as containers for interface signals, replacing internal bus objects. This is a breaking change that affects all of the constructors that previously accepted separate entity and name parameters.
• Properly implement resets
• Store simulation time in AxiStreamFrame
• Add tx_complete field in AxiStreamFrame
