Help:DE4 can't run simple socket server normally

Although the design is now working, I recommend analysing and solving those critical warnings.

Keeping them probably doesn't hurt for test purposes, but can lead to very tricky problems if you deploy the design on the field and go into production.

Problems could occur when you use a different speed grade device, work near the temperature range limits or simply get FPGAs coming with a different production site and this may lead to slightly changes in typical values of your current device.
