All notable changes to this project will be documented in this file.
The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.
- Remove extra files in Bender.yml
- Use pulp-io for peripherals -> updated udma subsystem and corresponding peripherals
- Use new gpio peripheral
- Externalize clock generator modules
- Remove IPApproX support
- Clean up & update dependencies
- Update AXI to TCDM IPs
- Bump cv32e40p to pulpissimo-v4.1.0 (Unlock all interrupts and increases fpu latency)
- Update jtag_pulp to v0.2.0
- Use PULP Platform IDCODE
- tcdm_err_slave: stall r_opc for 1 cycle
- Various synthesis fixes
- Add obi adapter also to core data path
- Fix debug module addresses
- Update RI5CY to CV32E40P
- Remove PULP_TRAINING references
- Wire up uart char and error events
- Update riscv-dbg to v0.5.0 (synchronous jtag reset and bus error signaling)
- Update bender dependency link for udma components, ibex, cv32e40p
- Update interface for udma_i2c with unconnected
nack
- Fix ibex register file for FPGA
- Fix cdc reset signal for cluster
- Added simulation stdout (replacing the hierarchical access in the tb hack)
- Removed apb_timer (duplicate)
ips_list.ymlhas missing domain tags causing trouble with the FPGA flow- Bumped fpnew for
common_cellsdeps
- Added support for Hyperbus. pulp_soc now supports booting from HyperFlash memory
- Increase size of boot_mode signal to 2-bit to accomodate the new Hyperbus bootmode
- Bumped riscv_dbg IP Version to 0.4.1
- Switched to new AXI CDC IPs between SoC and Cluster
- Switched to common cells CDC for cluster event exchange
- Bumped axi IP Version to 0.29.1
- Reduced latency of APB and AXI transactions
- Bumped register interface IP Version to 0.3.1
- Bumped cv32e40p IP Version to pulpissimo-v3.4.0-rev3
- Bumped udma_core IP version to 1.1.0
- Switched to new I2C peripheral version with command stream interface
- Removed APB Bus interface from repository. The identical version defined in the APB depedency is now used
- Removed dependency to archived legacy axi_slice_dc
- Removed ifdef for separate FPGA RAM instantiation. This is now supposed to be handled by tc_sram wrapping a Xilinx XPM.
- Fixed Genus SystemVerilog incompatibility in soc_interconnect
- Added
Bender.ymlfile for bender compatibility - Added
obi_pulp_adapter
- updated
ibex - change from deprecated
generic_memorytotc_sramtech cell, bumptech_cells_genericaccordingly - Expose L2 Bank sizes to improve consistency
- updated
apb_fll_if, removed local interface definition to use the one defined externally - updated
hwpe-mac-engine
- Changed address aliasing rules to be identical to the behavior of the legacy interconnect.
- Fix wrong address part select in SRAM wrappers that caused part of the memories to be inaccessible and alias into lower address ranges.
- Completely replaced
soc_interconnectwith a new parametric version - Added AXI Crossbar to
soc_interconnectto attach custom IPs - Added new
pulp_socparameter to isolate the axi plug CDC fifo in case it is not needed - Add
register_interfaceas dependency to simplify integration of custom ip using reggen - Properly assert
r_opcsignal in new interconnect to indicate bus errors - Add error checking for illegal access on HWPE ports which only have access to L2 interleaved memory
- AXI ID width of cluster plugs are now set to actually required width instead of a hardcoded one
- TCDM protocol to SRAM specific protocol is moved from interconnect to memory bank module
- obsolete
axi_nodedependency - obsolete header files
- Propagate
ZFINXparameter
- Bump
fpnewtov0.6.4
- Fix bad dependency of fpnew
- Bump
fpnewtov0.6.3
- Fix drive input address in bootrom
- Bump
