Additional configuration for the extra libraries and tools are at the bottom. + +First, set ``technology.sky130.sky130A/sky130_nda/openram_lib`` to the absolute path of the respective directories containing the Sky130 PDK and SRAM files. See the +`Sky130 Hammer plugin README `__ +for details about the PDK setup. + + +Synthesis +^^^^^^^^^ +.. code-block:: shell + + make syn tech_name=sky130 CONFIG=TinyRocketConfig + +Post-synthesis logs and collateral are in ``build/syn-rundir``. The raw quality of results data is available at ``build/syn-rundir/reports``, and methods to extract this information for design space exploration are a work in progress. + +Place-and-Route +^^^^^^^^^^^^^^^ +.. code-block:: shell + + make par tech_name=sky130 CONFIG=TinyRocketConfig + +After completion, the final database can be opened in an interactive Innovus session via ``./build/par-rundir/generated-scripts/open_chip``. + +Intermediate database are written in ``build/par-rundir`` between each step of the ``par`` action, and can be restored in an interactive Innovus session as desired for debugging purposes. + +Timing reports are found in ``build/par-rundir/timingReports``. They are gzipped text files. + +DRC & LVS +^^^^^^^^^ +To run DRC & LVS, and view the results in Calibre: + +.. code-block:: shell + + make drc tech_name=sky130 CONFIG=TinyRocketConfig + ./build/chipyard.TestHarness.TinyRocketConfig-ChipTop/drc-rundir/generated-scripts/view_drc + make lvs tech_name=sky130 CONFIG=TinyRocketConfig + ./build/chipyard.TestHarness.TinyRocketConfig-ChipTop/lvs-rundir/generated-scripts/view_lvs + +Some DRC errors are expected from this PDK, especially with regards to the SRAMs, as explained in the +`Sky130 Hammer plugin README `__. +For this reason, the ``example-vlsi-sky130`` script black-boxes the SRAMs for DRC/LVS analysis. + +Simulation +^^^^^^^^^^ +Simulation with VCS is supported, and can be run at the RTL- or gate-level (post-synthesis and post-P&R). The simulation infrastructure as included here is intended for running RISC-V binaries on a Chipyard config. For example, for an RTL-level simulation: + +.. code-block:: shell + + make sim-rtl CONFIG=TinyRocketConfig BINARY=$RISCV/riscv64-unknown-elf/share/riscv-tests/isa/rv64ui-p-simple + +Post-synthesis and post-P&R simulations use the ``sim-syn`` and ``sim-par`` make targets, respectively. + +Appending ``-debug`` and ``-debug-timing`` to these make targets will instruct VCS to write a SAIF + VPD (or FSDB if the ``USE_FSDB`` flag is set) and do timing-annotated simulations, respectively. See the ``sim.mk`` file for all available targets. + +Power/Rail Analysis +^^^^^^^^^^^^^^^^^^^ +Post-P&R power and rail (IR drop) analysis is supported with Voltus: + +.. code-block:: shell + + make power-par tech_name=sky130 CONFIG=TinyRocketConfig + +If you append the ``BINARY`` variable to the command, it will use the activity file generated from a ``sim--debug`` run and report dynamic power & IR drop from the toggles encoded in the waveform. + +To bypass gate-level simulation, you will need to run the power tool manually (see the generated commands in the generated ``hammer.d`` buildfile). Static and active (vectorless) power & IR drop will be reported. diff --git a/docs/VLSI/index.rst b/docs/VLSI/index.rst index 56e807e8..1758a65a 100644 --- a/docs/VLSI/index.rst +++ b/docs/VLSI/index.rst @@ -11,5 +11,6 @@ In particular, we aim to support the Hammer physical design generator flow.
