[1.9.0] - 2020-03-14

A more detailed account of everything included is included in the dev to master PR for this release: #486

TracerV + Flame Graph support from FirePerf ASPLOS 2020 paper (PR #496)
- Docs: https://docs.fires.im/en/latest/Advanced-Usage/Debugging-and-Profiling-on-FPGA/TracerV-with-FlameGraph.html
Pre-packaged AGFI for Gemmini NN accelerator

Significant overhaul / expansion of Debugging and Profiling on FPGA docs (PR #496)
- Link: https://docs.fires.im/en/latest/Advanced-Usage/Debugging-and-Profiling-on-FPGA/index.html
Unification of FireSimDUT with chipyard.Top, all default firesim configs are now extensions of default Chipyard configs (PR #491)
- Unification of Configs/Tops between Chipyard and FireSim. Arbitrary Chipyard designs can be imported into FireSim
- Users can define a FireSim version of a Chipyard config by building a TARGET_CONFIG that specifies WithFireSimDefaultBridges, WithFireSimDefaultMemModel, and WithFireSimConfigTweaks
- FireSimHarness moved to FireChip. Harness now uses Chipyard's BuildTop key to control which Top to build
- AGFI naming scheme changed. firesim -> firesim-rocket, fireboom -> firesim-boom
BridgeBinders system is now generalized as IOBinders for attaching Bridges to the target (PR #491)
Parallelized verilator Midas-level (ML) simulation compilation (PR #475)
Default fesvr-step size in ML simulation (PR #474)
- Passing no plusArg will have the same behavior as on the FPGA
Disable zero-out-dram by default; expose in config_runtime.ini (PR #506)
Update docs to note previously added suffixtag feature (PR #510)

Fixed synthesizing printfs at the top-level (PR #485)
Fixed FPGA-level simulation to properly generate GG-side PLL (PR #487)
Fixed a non-determinism bug due to unreset target-state (PR #499)
Fixed bug in ML-simulation of verilog black boxes in verilator (PR #499)
Fixed bug in manager that prevented use of f1.4xlarges with no_net_configs (PR #502)
Allow simulations without block devices (#519)

FireSimNoNIC design option removed, all examples now use FireSim design option
- Designs can specify inclusion/exclusion of NIC by setting icenet.NICKey, i.e. in TARGET_CONFIG rather than using a different design
