Read the XML file about architecture description (see details in :ref:`arch_generality`)
-``--file`` or ``-f`` Specify the file name
-``--verbose`` Show verbose log
write_openfpga_arch
~~~~~~~~~~~~~~~~~~~
Write the OpenFPGA XML architecture file to a file
-``--file`` or ``-f`` Specify the file name
-``--verbose`` Show verbose log
read_openfpga_simulation_setting
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Read the XML file about simulation settings (see details in :ref:`simulation_setting`)
-``--file`` or ``-f`` Specify the file name
-``--verbose`` Show verbose log
write_openfpga_simulation_setting
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Write the OpenFPGA XML simulation settings to a file
-``--file`` or ``-f`` Specify the file name
-``--verbose`` Show verbose log
link_openfpga_arch
~~~~~~~~~~~~~~~~~~
Annotate the OpenFPGA architecture to VPR data base
-``--activity_file`` Specify the signal activity file
-``--sort_gsb_chan_node_in_edges`` Sort the edges for the routing tracks in General Switch Blocks (GSBs). Strongly recommand to turn this on for uniquifying the routing modules
-``--verbose`` Show verbose log
write_gsb_to_xml
~~~~~~~~~~~~~~~~
Write the internal structure of General Switch Blocks (GSBs) across a FPGA fabric, including the interconnection between the nodes and node-level details, to XML files
-``--file`` or ``-f`` Specify the output directory of the XML files. Each GSB will be written to an indepedent XML file
-``--verbose`` Show verbose log
..note:: This command is used to help users to study the difference between GSBs
check_netlist_naming_conflict
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Check and correct any naming conflicts in the BLIF netlist
This is strongly recommended. Otherwise, the outputted Verilog netlists may not be compiled successfully.
..warning:: This command may be deprecated in future when it is merged to VPR upstream
-``--fix`` Apply fix-up to the names that violate the syntax
-``--report <.xml>`` Report the naming fix-up to a log file
pb_pin_fixup
~~~~~~~~~~~~
Apply fix-up to clustering nets based on routing results
This is strongly recommended. Otherwise, the bitstream generation may be wrong
..warning:: This command may be deprecated in future when it is merged to VPR upstream
-``--verbose`` Show verbose log
lut_truth_table_fixup
~~~~~~~~~~~~~~~~~~~~~
Apply fix-up to Look-Up Table truth tables based on packing results
..warning:: This command may be deprecated in future when it is merged to VPR upstream
-``--verbose`` Show verbose log
.._cmd_build_fabric:
build_fabric
~~~~~~~~~~~~
Build the module graph.
-``--compress_routing`` Enable compression on routing architecture modules. Strongly recommend this as it will minimize the number of routing modules to be outputted. It can reduce the netlist size significantly.
-``--duplicate_grid_pin`` Enable pin duplication on grid modules. This is optional unless ultra-dense layout generation is needed
-``--load_fabric_key <xml_file>`` Load an external fabric key from an XML file.
-``--generate_fabric_key`` Generate a fabric key in a random way
-``--write_fabric_key <xml_file>`` Output current fabric key to an XML file
-``--frame_view`` Create only frame views of the module graph. When enabled, top-level module will not include any nets. This option is made for save runtime and memory.
..warning:: Recommend to turn the option on when bitstream generation is the only purpose of the flow. Do not use it when you need generate netlists!
..note:: This is a must-run command before launching FPGA-Verilog, FPGA-Bitstream, FPGA-SDC and FPGA-SPICE
write_fabric_hierarchy
~~~~~~~~~~~~~~~~~~~~~~
Write the hierarchy of FPGA fabric graph to a plain-text file
-``--file`` or ``-f`` Specify the file name to write the hierarchy.
-``--depth`` Specify at which depth of the fabric module graph should the writer stop outputting. The root module start from depth 0. For example, if you want a two-level hierarchy, you should specify depth as 1.
-``--verbose`` Show verbose log
..note:: This file is designed for hierarchical PnR flow, which requires the tree of Multiple-Instanced-Blocks (MIBs).
