OpenFPGA provides `bash`/`zsh` shell-based shortcuts to perform all essential functions and navigate through the directories. Go to the OpenFPGA directory and source ``openfpga.sh``

OpenFPGA provides `bash`/`zsh` shell-based shortcuts to perform all essential functions and navigate through the directories. Go to the OpenFPGA directory and source ``openfpga.sh``,

.. code-block:: bash

cd ${OPENFPGA_PATH} && source openfpga.sh

.. note::
|

The OpenFPGA shortcut works with only a bash-like shell. e.g., `bash`/`zsh`/`fish,` etc.

for example ``create-task _my_task_copy basic_tests/generate_fabric`` create a copy of the ``basic_tests/generate_fabric`` task in
|
||||
the current directory with ``_my_task_copy`` name.
|
||||
|
||||
.. option:: run-modelsim
|
||||
.. option:: goto_task <task_name> <run_num[default 0]>
|
||||
|
||||
This command navigate shell to specific run-directory of the given task.
|
||||
For example `goto_task lab1 2` will change directory to `run002` runt directory of `lab2`
|
||||
|
||||
.. option:: clear-task-run <task_name>
|
||||
|
||||
Clears all run diretories of the given task
|
||||
|
||||
.. option:: run-modelsim <task_name>
|
||||
|
||||
This command runs the verification using ModelSim.
|
||||
The test benches are generated during the OpenFPGA run.
|
||||
**Note**: users need to have ``VSIM`` installed and configured
|
||||
|
||||
|
||||
.. option:: run-regression-local
|
||||
|
||||
This script runs the regression test locally using the current version of OpenFPGA.

- Routing architecture: L = 4, fc_in = 0.15, Fc_out = 0.1
|

<!-- VB & JL: Using Ian Kuon's transistor sizing and drive strength data for routing, at 40 nm. Ian used BPTM
|
||||
models. We are modifying the delay values however, to include metal C and R, which allows more architecture
|
||||
experimentation. We are also modifying the relative resistance of PMOS to be 1.8x that of NMOS
|
||||
(vs. Ian's 3x) as 1.8x lines up with Jeff G's data from a 45 nm process (and is more typical of
|
||||
45 nm in general). I'm upping the Rmin_nmos from Ian's just over 6k to nearly 9k, and dropping
|
||||
RminW_pmos from 18k to 16k to hit this 1.8x ratio, while keeping the delays of buffers approximately
|
||||
lined up with Stratix IV.
|
||||
We are using Jeff G.'s capacitance data for 45 nm (in tech/ptm_45nm).
|
||||
Jeff's tables list C in for transistors with widths in multiples of the minimum feature size (45 nm).
|
||||
The minimum contactable transistor is 2.5 * 45 nm, so I need to multiply drive strength sizes in this file
|
||||
by 2.5x when looking up in Jeff's tables.
|
||||
The delay values are lined up with Stratix IV, which has an architecture similar to this
|
||||
proposed FPGA, and which is also 40 nm
|
||||
C_ipin_cblock: input capacitance of a track buffer, which VPR assumes is a single-stage
|
||||
4x minimum drive strength buffer. -->

<!-- VB: the mux_trans_size and buf_size data below is in minimum width transistor *areas*, assuming the purple
|
||||
book area formula. This means the mux transistors are about 5x minimum drive strength.
|
||||
We assume the first stage of the buffer is 3x min drive strength to be reasonable given the large
|
||||
mux transistors, and this gives a reasonable stage ratio of a bit over 5x to the second stage. We assume
|
||||
the n and p transistors in the first stage are equal-sized to lower the buffer trip point, since it's fed
|
||||
by a pass transistor mux. We can then reverse engineer the buffer second stage to hit the specified
|
||||
buf_size (really buffer area) - 16.2x minimum drive nmos and 1.8*16.2 = 29.2x minimum drive.
|
||||
I then took the data from Jeff G.'s PTM modeling of 45 nm to get the Cin (gate of first stage) and Cout
|
||||
(diff of second stage) listed below. Jeff's models are in tech/ptm_45nm, and are in min feature multiples.
|
||||
The minimum contactable transistor is 2.5 * 45 nm, so I need to multiply the drive strength sizes above by
|
||||
2.5x when looking up in Jeff's tables.
|
||||
Finally, we choose a switch delay (58 ps) that leads to length 4 wires having a delay equal to that of SIV of 126 ps.
|
||||
This also leads to the switch being 46% of the total wire delay, which is reasonable. -->

<!--- Area calculation: Total Stratix IV tile area is about 8100 um^2, and a minimum width transistor
|

area is 60 L^2 yields a tile area of 84375 MWTAs.
|
||||
Routing at W=300 is 30481 MWTAs, leaving us with a total of 53000 MWTAs for logic block area
|
||||
This means that only 37% of our area is in the general routing, and 63% is inside the logic
|
||||
block. Note that the crossbar / local interconnect is considered part of the logic block
|
||||
area in this analysis. That is a lower proportion of of routing area than most academics

assume, but note that the total routing area really includes the crossbar, which would push

routing area up significantly, we estimate into the ~70% range.
