PROCESSING VECTOR DATA
Applied to OVF time stamps:
Time = ovf_time * scale + time_offset
SCALE & TIME_OFFSET
Read pin states from OVF. ADD_PIN states also evaluated.
PIN STATES READ
ALIGN_TO_CYCLE, AUTO_ALIGN and TEMPLATE_CYCLIZATION. Converts print-on-change to cycle vectors.
Process BIDIRECT_CONTROL or BIDIRECT_STATES. Separates in/out data on bidirects if data is merged in OVF. Not necessary for most canned readers (however, is required for Verilog VCD). Note states used are prior to STATE_TRANS.
Process PINTYPE, EDGE_SHIFT and EDGE_ALIGN commands. Moves timing edges or adds timing to vectors. Inhibited if SEPARATE_TIMING command present.
Process MASK_PINS commands to force pins to specified states within time windows or based upon other pin states (OVF states).
