Good idea!

But it doesnt work, how we think. I use fifoed avalon uart and when i connect rx and tx to uart, it takes about 480LEs. When i disconnect rx or tx from uart, it takes about 470-480LEs, too. When i dont use fifo for tx or rx in settings in QSYS, it takes about 370-380LEs. But it is only about 100LEs fewer than all connect uart. Why so few ?
