There is one important thing missing from the pics right now which I have been meaning to put in for a while, which is a clock divider property which could allow at least the PICS to run at different clocks at multiples of the basic clock. You could be right, VBB may not stretch to what you have in mind.

From the screenshot, I don't know how it can be used to generate multiple clock domain VHDL testbench. I used to do ASIC work, but most of that was single clock and asynch stuff, making TB creation fairly easy. With multiple clocks and bus masters, I must check all signals and their tri-state status. ----- Original Message ----- From: "James Caska" To: Sent: Saturday, November 03, 2001 3:52 PM Subject: Re: [EE]: VHDL testbenches > In case where you were wondering where Virtual Breadboard was (forgot to > mention it)... > > http://www.virtualbreadboard.com > > Regards, > James Caska > caska@virtualbreadboard.com > ujVM - 'The worlds smallest java virtual machine' > > -----Original Message----- > From: pic microcontroller discussion list > [mailto:PICLIST@MITVMA.MIT.EDU]On Behalf Of James Caska > Sent: Sunday, 4 November 2001 10:39 AM > To: PICLIST@MITVMA.MIT.EDU > Subject: Re: [EE]: VHDL testbenches > > > With a bit of tweaking, perhaps writing a custom component or two I am > pretty sure you could generate a testbench in Virtual Breadboard. > > It depends if the PICs you are using are supported, and what your timeframe > is > > Virtual Breadboard V1.1 !New Version supports > PIC16F877,F8X,16C71X,16C5X,12C5XX > > You may need to write a "Emulator" for your VHDL tester as a custom VBB > component as a starter though.
