[> 2020.XX, planned for July 2020 --------------------------------- [> Issues resolved ------------------ - Fix flush_cpu_icache on VexRiscv. [> Added Features ------------------ - JTAG UART with uart_name=jtag_uart (validated on Spartan6, 7-Series, Ultrascale(+)). - Add CV32E40P CPU support (ex RI5CY). - Use InterconnectPointToPoint when 1 master,1 slave and no address translation. - Improve WishboneBridge. - Improve Diamond constraints. - Add LedChaser on boards. - Speedup Memtest using an LFSR. - Add Microwatt CPU support (with GHDL-Yosys-plugin support for FOSS toolchains). - Improve boards's programmers. - BIOS history, autocomplete. - Pluggable CPUs. - Add nMigen dependency. - Properly integrate Minerva CPU. [> API changes/Deprecation -------------------------- - Add --build --load arguments to targets. - Deprecate soc.interconnect.wishbone.UpConverter (will be rewritten if useful). - Deprecate soc.interconnect.wishbone.CSRBank (Does not seem to be used by anyone). - Move soc.interconnect.wishbone2csr.WB2CSR to soc.interconnect.wishbone.Wishbone2CSR. - Move soc.interconnect.wishbonebridge.WishboneStreamingBridge to soc.cores.uart.Stream2Wishbone. [> 2020.04, released April 28th, 2020 ------------------------------------- [> Description -------------- First release of LiteX and the ecosystem of cores! LiteX is a Migen/MiSoC based Core/SoC builder that provides the infrastructure to easily create Cores/SoCs (with or without CPU). The common components of a SoC are provided directly: - Buses and Streams (Wishbone, AXI, Avalon-ST) - Interconnect - Common cores (RAM, ROM, Timer, UART, etc...) - CPU wrappers/integration - etc... And SoC creation capabilities can be greatly extended with the ecosystem of LiteX cores (DRAM, PCIe, Ethernet, SATA, etc...) that can be integrated/simulated/build easily with LiteX. It also provides build backends for open-source and vendors toolchains.
