A collection of big designs to run post-synthesis simulations with yosys
A collection of larger designs to run post-synthesis simulations for testing yosys. Type 'make -j8 full' to run all tests and use max. 8 parallel threads. Currently included designs: --------------------------- openmsp430: http://opencores.org/project,openmsp430 aes_5cycle_2stage: http://opencores.org/project,aes-encryption softusb_navre: http://opencores.org/project,navre amber23: http://opencores.org/project,amber lm32: https://github.com/m-labs/lm32/ verilog-pong: https://github.com/yzheng624/verilog-pong elliptic_curve_group: http://opencores.org/project,ecg reed_solomon_decoder: http://opencores.org/project,reed_solomon_decoder bch_verilog: https://github.com/russdill/bch_verilog Adding new designs to this collection: -------------------------------------- Designs must come with a useful testbench. Synthesis and testing should not consume extraordinarily much CPU time compared to the existing test cases. Test cases that expose existing yosys bugs are welcome. Test cases that fail because of missing yosys features or glitches in simulation with icarus verilog will not be included. Each design has its own top level directory with the following layout: <design_name>/rtl/ directory with the RTL verilog files <design_name>/sim/ directory with the test bench and auxilary files <design_name>/sim/settings.sh a simple shell snippet that set the following variables: TOP="..." name of the top entity in the design RTL="..." list of RTL files in the rtl/ directory (without path) SIM="..." list of addition testbench verilog files in the sim/ directory (without path) <design_name>/sim/build.sh (optional) script for re-generating additional testbench files (such as firmware ROM images). this script, by convention, is called from within the sim/ directory The testbench top entity must be named 'testbench'. The rtl/ and sim/ directory are both in the include path for simulation and synthesis. Have a look at the 'softusb_navre' design for a simple example. The DESIGNS variable in the Makefile has a list off all designs used for the test. All new design there, or set the variable to individual designs for testing purposes.
