        Extend optimization 42 target period span
    
        * extended range from 0.5 to 10ns (2GHz - 100MHz)
        * increased step size to 0.25ns => 38 measurements
        * fixed bug in optimization level 1/2 settings
        * improved O3 level to even more aggressive settings
        * added sweep, remapping and constant propagation to initial netlist

        Re-activate normal evaluation
    
        * fixed optimization 42 implementation: normal runs (O != 42) are
          executed in single run mode
        * fixed bug with SAIF reading
        * fixed common_ip bug

        Fix O-level iterations
    
        * O-level iterations included only the synthesis phase, not PnR; thus
          PnR was always done on O0 synthesis results
        * fixed - PnR is now included in loop

        WIP: Implement special synthesis optimization evaluation level
    
        * level 42 activates a sweep search that iterates over
            - clock periods 0.5 - 5 (0.125 steps)
            - optimization levels 3 - 0
        * it also logs the runtimes of each step and outputs them in a
          synthesis_runtimes.tsv file
        * resulting WNS is logged in synthesis_results.tsv for each step
        * useful for analysis of evaluation runs
        * careful - regular evaluation is currently broken by the changes

        WIP: define optimization levels during evaluation
    
        * evaluation results are too conservative w.r.t. f_max
        * adding new --optimization flag for import task that defines gcc-like
          opt levels, which activate different synth + pnr options
        * Tcl does not work yet
