v2.0.0

Added

• Added support for Single-Data-Rate (SDR) PHY option for simpler links.

Changed

• Breaking: Renamed all serial_link_* IP modules and files to slink_* (e.g., serial_link.sv -> slink.sv, serial_link_physical.sv -> slink_phys_layer.sv). Users instantiating the core will need to update module names.
• Breaking: Migrated register generation from reggen to systemRDL and changed the register interface to APB. This updates the register memory map headers and RTL files (slink_reg.sv, slink_reg_pkg.sv).
• Breaking: Renamed the occamy_wrapper module to slink_isolate to reflect its general utility for isolation in other projects.
• Architecturally renamed the "network layer" to the "protocol layer" (slink_prot_layer).
• Removed internal axis dependencies and axi_channel_compare in favor of their upstream versions, and shifted to a cleaned-up internal wiring architecture.
• Cleaned up the slink_pkg package by removing redundant or obsolete constants and types.
• Replaced the project Makefile with a justfile for build automation.
• Switched to uv for handling Python dependencies, replacing the standard pip/requirements.txt workflow.
• Testbenches are no longer automatically imported under the Bender simulation target.
• Migrated project license checking to REUSE.

Fixed

• Breaking: Fixed the ddr_sel output path in the PHY with a tc_clk_mux2. This means users will need to make sure to have a tc_clk_mux2 technology cell specified for FPGA or ASIC implementations.
• Fixed testbench port

v1.1.2

Changed

• Removed ternary statement in serial_link_physical for better EDA tool compatibility.

v1.1.1

Changed

• The DDR output data is now muxed by a normal signal instead of a clock signal. Some tools infer a clock gate when a clock signal is used as a mux select signal.

v1.1.0

Changed

• Renamed clock division configuration registers to deliberately introduce breaking changes when using the old incorrect configuration registers.

Fixed

• SW Clock division configuration

v1.0.1

1.0.1 - 2023-03-13

Changed

• Added NoRegCdc parameter to serial_link module to disable the CDC between the RegBus Clock and the System Clock
