    Urgent: Async system design

    Hey guys...well, im in a soup....and i need help quite urgently!!! I had a post about this same topic b4...quite sometime back... It is about this async system that i plan to design. The idea was to design an async ALU....a simple one albeit...but one which cud demonstrate the gr8 possibilities...

    no simulation for counter in modelsim!!!!

    hey nand_gates..thanks a lot for showing interest and helping me with my project. sorry for this but i got this one last problem...i dont quite know verilog the way i know vhdl and hence i really cant totally comprehend the test_bench that u've provided. if u cud plz suggest any way to convert...

    no simulation for counter in modelsim!!!!

    yeah..right ..i think i shud have done the first time itself...haha ok...this is the link..it's a rapidshare link/.. https://rapidshare.com/files/1299703/mini.rar it's actually a collection of all my project files.... proc is the main vhd file---my simple processor... i havent included my...

    no simulation for counter in modelsim!!!!

    wel...the clear signal i use is generated by completion of an instruction. The project is a simple processor, implemented using the basic idea presented in morris mano "digital design"...where a timing decoder is used to generate a sequence of time cycles during which a given micro-instruction...

    no simulation for counter in modelsim!!!!

    thx for the prompt reply...i tried the high pulse on clr and it worked just liked u said it would. however, i still have a problem 'cause the upcounter( 2bit in this case) is supposed to work as an input to a decoder(2to4) to generate a timing cycle sequence T0,T1,T2,T3. Now,Clr signal is...

    an asynchronous multiplier!!!

    well....i mean....normally in async systems...the whole adder or multiplier can be built as an asycn system....but also...we can use the blocks for each operation and then maybe use Hand shaking signals to pass on the results ...i mean communicate. u cud chk any literature on async systems and...

    an asynchronous multiplier!!!

    hey guys... well...i've finally begun work on my asynchronous ALU...while add/sub seems sorted out for now...i need some help as to how to begin with a multiplier...i dont plan to integrate a divide unit. Also, while there r ieas to directly build an async add/sub systtem...i recently cam...
