+# Regression tests for OpenFPGA
+The regression tests are grouped in category of OpenFPGA tools as well as integrated flows.
+The principle is that each OpenFPGA tool should have a set of regression tests.
+
+- compilation\_verfication: a quicktest after compilation
+
+- Basic regression tests should focus on fundamental flow integration, such as
+
+  - Yosys + VPR + OpenFPGA for a Verilog-to-Verification flow-run
+
+- FPGA-Verilog regression tests should focus on testing fabric correctness, such as 
+
+  - VPR + OpenFPGA integration for a BLIF-to-Verification flow-run
+
+
+- FPGA-Bitstream regression tests should focus on testing bitstream correctness and runtime on large devices and benchmark suites
+
+- FPGA-SDC regression test should focus on SDC file generation and necessary syntax check
+
+- FPGA-SPICE regression test should focus on SPICE netlist generation / compilation and SPICE simulations qwith QoR checks.
+
+
+Please keep this README up-to-date on the OpenFPGA tools
