Delaware growers are the first on the East Coast able to take advantage of a new online tool that helps protect sensitive crops from pesticides that may drift due to wind or weather. Delaware is the newest participant in the DriftWatch program, which allows growers of certain crops or commercial beekeepers to alert pesticide applicators of sensitive areas before they spray.

The Delaware Forest Service (DFS) has unveiled a new online tool that uses geographic information systems (GIS) software to help cities, towns, and neighborhoods to measure and increase their community tree canopy percentage. The link is: de.gov/treecanopy Developed by the Delaware Department of Agriculture's GIS specialist Jimmy Kroon, the tool covers the entire First State: municipalities as well as homeowner associations and neighborhoods can assess their current level of tree cover as a starting point to explore opportunities to plant new trees and maintain their existing ones.

A few days ago China sent a survey team to study Mt. Everest, today they reached the Advanced Base Camp at 6,500m (21,300ft). What's interesting about this expedition (besides the scientific work that it will do) is that two photographers, Li Pu and Cai Qing, used two Honor phones to capture some beautiful shots. One of these was the Honor X10 5G, which hasn't been officially announced yet (so these are the first official camera samples from the phone). The five shots have 10MP resolution, since pixel binning was used - the X10 will feature a custom Sony IMX600ysensor with 40MP raw...

Hi,

  I wanted to open a discussion on the stylus flowtool.  My purpose is to see if there are users out there who are having success with the tool.  To have some discussions around issues that I am running into and to get a user point of view on the problems I am trying to solve.

  Let's start the conversation with : Is there anyone out there trying to use flowtool?  Do you have a centralized flow, or each user has their own?

Thanks, and I look forward to the conversations...

hello sir this is Ganesh  from NIT Hamirpur pursuing MTech in VLSI. I have doubt regarding SDF i'm using genus tool for synthesis & after synthesis when i'm generating SDF it is giving delays by default for maximum values but i want all the delays like minimum:Typical:Maximum how can i do this. Is there any provision to set PVT values manually for SDF generation so that i can get all the delay values.

Hi all,

I need to develop a digital design/verification solution to compile,elaborate and simulate SV designs (basically a complex xrun wrapper). I am an experienced user of xrun and I have done a number of these wrappers over the years but this one is to be more of a tool, intented to be used Company-wise, so it needs to be very well thought and engineered.

It needs to be robust, simple and extensible. It needs to support multi-snapshot elaboration, run regressions on machine farms, collect coverage, create reports, etc.

I've been browsing the vast amount of documentation on XCELIUM and, although very good, I can't find any document which puts together all the pieces of what I am trying to achieve. I suppose I am more clear on the elaboration, compilation and simulation part but I am really lacking on the other areas like : LSF, regressions coverage, where does vManager fits in all this, etc.

I'd appreciate if someone can comment on whether there is a document which depicts how such a DV flow can be put together from scratch, or whether there is a kind of RAK with some example xrun wrapper.

Thanks

Hello All,

starting with version 8.1 the contents of the ce_tools directory will no longer
be shipped with Specman. The directory contains some unsupported AE/R&D
ware and has not been updated for several releases (i.e. most of those old
packages don't work with the latest release).
 
Attached is the contents of this directory. Please read the README before
using any of the packages.

Hello,

I am trying to import multiple verilog modules defined in a single file with "`define" directive in the top using Verilog In. The code below is an example of what my file contains.

When I use the settings below to import the modules into a library, it imports it correctly but completely ignores all `define directive; hence when I simulate using any of the modules below the simulator errors out requesting these variables.

My question: Is there a way to make Verilog In consider `define directives in every module cell created? 

Code to be imported by Cadence Verilog In:

Hi, 

I want my layout verified by Quantus QRC. But, I can't find the tool bar on the option list ( as show in the picture)

I have tried to install EXT182 and configured it with iscape already, and also make some path settings on .bashrc, .cshrc. But, when I re-source .cshrc and run virtuoso again, I just can't find the toolbar. 

If you have some methods, please let me know.

Thanks a lot!

Appreciated

My virtuoso version is: ICADV12.3
