Quicklogic FPGA Toolchain

Contains SymbiFlow toolchain release packages for Quicklogic FPGAs

This guide describes everything you need to set up your system to develop for QuickLogic FPGA Toolchain. Currently, the SymbiFlow Installer runs only on Linux 64bit.

Note: Place a request for the installers that support QLF-K4N8 and QLF-K6N10. For EOS-S3 devices, the Release tag has installer which can be downloaded.

Symbiflow supports these QuickLogic devices - QLF-K4N8, QLF-K6N10 and EOS-S3

For more details on the symbiflow options refer the tutorial guide: Symbiflow_Tutorial

Ways to run Symbiflow on these devices are explained in the following sub-sections:

QLF-K4N8/QLF-K6N10 Device:

Below are some ways to run SymbiFlow for QLF-K4N8/QLF-K6N10 Devices:

1. Run an installer and run an example
2. Compile from source code and run example

1) Run an installer and run an example

2) Compile from source code and run example

This release package contains the following GitHub repositories that are compiled to create this package.

You may use the following command to get the source, compile and install it:

#Checkout *symbiflow-arch-defs* repository (https://github.com/QuickLogic-Corp/symbiflow-arch-defs.git), branch: **master**.
git clone https://github.com/QuickLogic-Corp/symbiflow-arch-defs.git
cd symbiflow-arch-defs
make env
cd build;make all_conda

#Run any test case in the current terminal window. For example, follow these steps to run a test case:
cd build/quicklogic/<device>/tests/design_flow/counter_16bit
#For qlf_k4n8
make counter_16bit-umc22-adder_route
#For qlf_k6n10
make counter_16bit-gf12-adder_route

EOS-S3 Device:

Below are some ways to run SymbiFlow for EOS-S3 Device:

1. Run an installer and run an example
2. Compile from source code and run example
3. Run SymbiFlow in a container

For details on the usage of RAM, FIFO and Multiplier blocks, refer to the following document: Ram_Fifo_Mult_User_Document

NOTE:

While running the compilation with the latest toolchain (v1.3.1), the following warning would be seen:

fasm/fasm/parser/__init__.py:27: RuntimeWarning:
Falling back on slower textX parser implementation:
  ImportError: cannot import name 'tags' from 'fasm.parser' (/path/to/toolchain/install/quicklogic-arch-defs/tests/counter_16bit/fasm/fasm/parser/__init__.py)
Please install all dependencies and reinstall with:
  pip uninstall
  pip install -v fasm
  '  pip install -v fasm'.format(e), RuntimeWarning)
['textx']

This is due to recent changes in the Symbiflow fasm which adds support for the antlr parser in place of textx.

This is not a problem, and current installation will continue to use textx as the parser, as with previous releases.

antlr installation requires a few extra steps, which needs to be integrated into the toolchain installation.

This is not yet incorporated in the current install, and will be added in a future release.

Manual Installation of antlr can be done from the instructions at the Symbiflow fasm readme.

A brief of the steps for manual installation (optional), after toolchain installation is completed:

• Ensure conda activate is executed

• Execute the following sequence

  cd $INSTALL_DIR
  git clone https://github.com/SymbiFlow/fasm.git
  cd fasm
  git submodule update --init
  sudo apt install cmake default-jre-headless uuid-dev libantlr4-runtime-dev
  make build
  python setup.py test
  

• If all goes well, run the below to test:

  python3 -c "import fasm.parser as p; print(p.available)"
  

  An output similar to below:

  ['antlr', 'textx']
  

  indicates that antlr is now installed and available, and will be used as the default parser.

1) Run an installer and run an example

Download Symbiflow_v1.3.2

This package installs these toolchains :

• Yosys
• Yosys-Plugins
• VTR
• iverilog
• Architecture definitions installation

Steps:

• Install

export INSTALL_DIR="specify the installpath"
bash Symbiflow_v1.3.2.gz.run

• Initialize

export INSTALL_DIR="specify the installpath"
export PATH="$INSTALL_DIR/quicklogic-arch-defs/bin:$INSTALL_DIR/quicklogic-arch-defs/bin/python:$PATH"
source "$INSTALL_DIR/conda/etc/profile.d/conda.sh"
conda activate

• Run help command

ql_symbiflow -h

• Run Example Design

  The example designs are provided in separate directories at $INSTALL_DIR/quicklogic-arch-defs/tests :

  1. counter_16bit - simple 16-bit up-counter. The design targets the device ql-eos-s3 and package PD64.

  To run this example, run following commands:

  cd $INSTALL_DIR/quicklogic-arch-defs/tests/counter_16bit
  ql_symbiflow -compile -d ql-eos-s3 -P pd64 -v counter_16bit.v -t top -p chandalar.pcf
