BSGEN has been implemented with an open architecture. BSGEN reads VHDL source for BS cells from selected library directory below install directory. User can define new libraries with different cell styles or clocking. Two libraries are included in the basic release: basic library without INTEST and BIST features and its synchronized version.
Top level part of the compiled VHDL model can be used as a symbol for schematic work when connecting JTAG implementation of the ASIC core to the pads of the ASIC.
BSGEN also allows clocking strategies with boundary scan register. Clock skew for a long register (flip flop for each ASIC I/O pin) can be avoided by allowing BSGEN to split register to smaller parts which are separated with opposite clocked flip flop.
Availabilty: As a PC/DOS program license with or without Windows interface. GAWK filtersources available for processing input file from any ASCII-listing of pin names. Separate BSGEN compilations with technical consultation also available.
