  • Re: Using several operating conditions at the same time
     The only way to assign different operating conditions to different sections of the design - is to configure power domains.  For each power domain you can set a separate operating condition.   Some CPF is going to be required in order to establish the membership - which parts of the design are associated with each power ...

  • Re: Timing analysis on partitioned design in EDI
    It sounds like some of your clock trees are still in ideal mode.  Try running the following to find all clock endpoints that are not receiving a propagated clock: encounter 2> check_timing -check_only clock_not_propagated -verbose ############################################################### #  Generated ...

  • Re: Given the net name how do weget to know for which pin it connects
    Most of the replies so far have been using FEDB side Tcl APIs.  The timing APIs also provide some functionality in this area:  [DEV]encounter 3> set collectionOfPinObjects [get_pins -of_objects [get_nets clk_3_1]]  0x4 [DEV]encounter 4> query_objects $collectionOfPinObjects C3_2/A C3_1/Y If you want a more human readable ...

  • Re: Encounter 8.1 vs 9.1 sdf generation
    We made a switch in the Encounter platform from using SDF generated by the delayCal command and that produced by the write_sdf command.  All new development on SDF will be using write_sdf - this is different code that delayCal - and thus has some different - generally better behaviors. In bcWc mode, the software is computing two corners ...

  • Re: Command for getting only the si delay
    You can also use the  timing Tcl API to query the net arcs directly for the delta delay values:       set delta_delay_max_rise  [get_property [get_arcs -from U1/Y -to U2/A] delta_delay_max_rise]   There are similar properties for min delays and for falling delays.  Refer to the get_property command which is ...

  • Re: Typical value Missing in the triplets in a generated SDF File
     SignalStorm stand-alone delay calculation was capable of performing delay calculation for min,typ, and max at the same time - and provided facilities for controlling what when into the various SDF delay slots.  In ETS (and EDI), nonMMMC mode only supports two delay slots - best and worst under bcWc mode, and early/late under OCV mode - ...
