Problems fixed in IO Checker 4.0


SPRTitleReleasedDescription
2014 Verilog generated from PCB data contains wires declarations 4.0.1 Removed wires and generate ANSI style Verilog module
2012 MACHXO pins marked as dedicated control pins 4.0.1 MACHXO2 and MACHXO3 pins DONE, PROGRAMN and INNIT are set to be dedicated control (and not to be used in the constraints) while beeing dual use.
1977 Verify that the regular expression in rules dialog is valid 4.0.1 When you specify a regular expression like 'user_(\d+' there is no feedback that the expression is invalid. (Only that the match count will be 0)
1965 Wire both $LOCATION and LOCATION components 4.0.1 In some sheets in Cadence Allegro the FPGA components uses both LOCATION and $LOCATION reference designator. The wiring routine should support in the same sheet.
1942 Improve HDL/Constraint generation for Altium Designer LVDS signals 4.0.1 In Altium Designer it is required that all LVDS signal pairs end with _n and _p. This is also the case for array signals.
So an LVDS array of signals in Altium Designer looks like:
sig<4>_p, sig<3>_p, ... (and n side, a<4>_n , a<3>_n).
1923 Improve caption of verification window 4.0.1 IO Checker should adjust the caption when only doing a file status verification (vs a project verification).
1876 Add a check to verfiy all HDL signals have a location constraint 4.0.1 It is now only possible to see in the HDL Signal view if all signals have a pin location constraint. (Using the view filter).
1577 Improved generation of both HDL and constraint file from PCB data 4.0.1 HDL and constraint generation is now based on the Signal View. Here you can modify signal names, ranges and direction before generating HDL.
