As we all know that Synplicity had released it latest FPGA synthesis tool Synplify Premier 8.8 and using the new version of FlexLM 10.4.2 to encrypt the License file. The original user cannot upgrade to 8.8 any more without purchase the latest license from Synplicity. Who can provide their experience of running Synplify 8.8 in comparison with 8.6.2? Is their significant improvement on the QoR or whatever useful stuff?
