Forum Post: RE: Help for Regular Expression, thanks in advance!

First of all, why do you want to use regular expression for this? The matching is limited to 9 captured parts. Your example contains 8 parts, so that should be ok. A parseString() also does the job. If...

Forum Post: AMS simulation error after removing a verilogA cell from the...

Dear All, I was running a testbench in ADE with AMS engine. It had vHDL and verilogA modules. It was running fine. But when I removed the verilogA module (i.e. DCO present in VERILOG_A_MODULE_2...

Forum Post: RE: Error during ADE spectre simulation

300 for the start timeout is normally enough unless you're submitting via a queueing system and it's full and so jobs don't start. The thing I'd check first is whether you can run (in a terminal...

Well, the error is fairly clear. You've got nothing to LVS against because you don't have a schematic, and you don't have an auCdl view for it to stop at (presumably to use an external CDL netlist for...

Forum Post: RE: Verilog $random seems to be not random

You shouldn't give a new seed every time you call it as that would give a very non-random sequence. The original sequence was indeed random, but it's just that you're starting from a fixed seed (which...

I've not found any records of that error reporting issues with generated_skeleton_ahdl messages. I think this would be much easier to debug via customer support , as otherwise there would need to be...

Forum Post: RE: Trouble using pPar with Spectre simulation

Hi Alexandre, Can you please post lines 59-61 and 67-69 of the input.scs so it's clearer which lines are causing the problem? Ideally, if the circuit is just as you've shown it, providing the entire...

Forum Post: Re : I2C Routing SCL,SDA as 100ohm differential pair

Hi Folks, I have done many designs with I2C and routed SCL,SDA as 50ohm SE lines.Recently I have done this as 100ohm diff pair for one of our customer. Whether it is ok in-terms of functionality?

RS components not to support the link that CIP uses. EMA has no way of working past that for any distributor (Digikey and Mouser changes kept breaking things and CIP had to adapt.) I would recommend...

Forum Post: RE: Re : I2C Routing SCL,SDA as 100ohm differential pair

Most of the time, 100 ohm diff will still work. But, when it doesn't work, it will be intermittent and cause blood to shoot out of the ears of your software nerds. 100 diff pair advantages don't exist...

Forum Post: RE: Re : I2C Routing SCL,SDA as 100ohm differential pair

I2C can be routed as a diff pair, but with I2C you need to take into account "CrossTalk" between the clock and data line. You would want them separated so that crosstalk between the two lines is...
