Hi all,
I need to buy a PC for running (almost exclusively) Cadence
applications (mostly analog flow, but possibly also mixed-signal
projects in the near future). Our budget is not enough to get any SUN
workstation, so an x86 running linux is our only option. The problem
is that I am unsure about what are the most im****tant features I
should take into account when choosing the CPU...
For instance, I was unsure about the relative im****tance between CPU
speed vs. number of cores. As an example, what of the following would
be a better platform for running, say, large Spectre simulations?
-A 3.16GHz dual core (FSB 1333MHz) with 6MB of cache and 4GB of RAM
(fast, but just 2 cores)
-A 2.66GHz quad core (FSB 1333MHz) with 12MB of cache and 4GB of RAM
(slower, but with 4 cores & more cache)?
....I recall someone stating in this forum that "spice simulations are
as single-threaded as an application can be"... does this mean that
having more cores won't really improve performance appreciably, at
least when talking about Spectre simulations?
What about the requirements for other tasks, like DRC and synthesis?
Any advice is rather welcome!
Regards,
Jorge.
