Yes 'while', 'for', and 'repeat' are synthesizable in some tools (they work in Xilinx XST), however the synthesizer usually limits the loops to constants known at compile time, as FvM described. Remember that these are compile-time loops that create multiple copies of logic. They are not run-time loops that do things ... kevin hart laugh at my pain full movie free https://simobike.com
