clock skew is mainly delay in clock arrival between different points due to different clock network from clock source to those points.
clock uncertainty is variation in clock period for one point, regardless of other points.
RTL Vs Behavioral
Behavioral codes may be synthesizable or non-synthesizable. If you want to use tools like behavioral compiler to automatic scheduling and resource allocation, the code must be written with behavioral coding style.
I use in in some designs, the result is very interesting. But...
i/o asic pad
PAD insertion in ASIC is very differenent with FPGA. There is no good way for automatic pad insertion, instead designer may put each PAD in the top level netlist same as other blocks.
Also other PAD issues like power & ground, multi_supply pads, ESD rules, filler and breaker...
Does anyone installed Syn0psys Tetramax 2003/2004 on SuSE 9.1
I installed it in both overlay and standalone modes, but everytime when I run it, gives SEGMENTATION FAULT error.
I installed other synopsys 2003 tools on SuSE 9.1 and the work well. Can anybody help me?
It is just a question. I dont know if there is any practical example. As I know, in high temps. (ex. +125 oC) the devices are modeled for corner simulation for stress or life cycle test.
So what is the behavior of semiconductures, specially CMOS devices in very low temperatures? Are the PDKs...
power supply without transformer
I need a circuit for 5v/12v DC supply from 110/220 AC. The common way is to use a transformer, a bridge and a voltage regulator. I know this way, but it is needed to be done without using trans becasue of its weight. The maximum current is 500 mA. A...
Virtual Serial Port
I need to define a virtual serial (com) port which behaves like a real serial port.
Can anybody help me how can I do it?
I have found VSPD software and activex. But I want a free way.
Thanks a lot,
Re: SPW 4.8 on Solaris8
One way is to add new library manually. (create a directory in your [spwfiles] directory and add it to your cds.lib file inside [spwfiles].
For more information, refer to its manuals.
