Timing requirements to a part of a circuit

kaz, I'm using old version of cookbook (https://vk.com/doc-93602802_401608943?hash=1d128a921cdd322f95&dl=bd60b7ecbf49a6ca84), so there is some difference in projects, in old version they use pipelined multiplier, clocked by fast_clk. So when I click summary setup I can get some information about multiplier's set of registers. Of course if we use mult without pipelining we won't get any setup information. Which command is intended for enable only? OK, I'll look for it in Altera's documents...
