Hello,
I would like to ask if somebody know about library in VHDL/Verilog with soundly designed (and optimized) primitives of "sequential logic circuits" I mean basic "bricks" for elaborating more complicated sequential circuits. I mean library/package made by one of FPGA circuits vendors like Xilinx/Intel or verified open-source one. I seen such basic primitives in Intel "Quartus" software but these primitives had been available when user was using "Schematics Editor". I am interested in such library written in one of HDL languages. I found for example such simlpe definitions of T and D flip-flops. Here are examples:
Sorry for pasting images, but this definition I only have as an image available (it is citation from polish book about VHDL).
I mean library with all kind of flip-flops, counters, various type of registers (serial/parallel), frequency dividers etc. The best would be library/package with primitives from TTL low/medium ICs or CMOS4000 series. I mean also such bricks like "reverse counters" (with asynchronic reset,set) serial-parallel registers (also shift registers), simple ALUs,
Could someone to reccomend such library/package?
Thanks in advance and regards
