You can setup RapidWright such that it won't require network/Internet access. Try doing the following on a computer with Internet access:
To run the GUI in Linux after you have setup RapidWright in Windows, you not be able to run the DeviceBrowser since it requires a jar specific to the OS. Gradle will configure the jars to work for Windows if you set it up first there. You could avoid this by using Windows Subsystem for Linux to emulate a Linux environment, or you can download the jars directly from the release website: |

I have download the "rapidwright_data" file ( only [RapidWright 2024.1.1-beta Release](rapidwright_data.zip not data2.zip) and replaced the file in the /RapidWright/data, then I run this command But the "parts.db" is in the data folder, it looks like I run this command still need network, so what command should I run? about the RWRoute and other command. Another question : rapidwright_data.zip (2024.1.1)== rapidwright_data.zip(2024.1.0)+ rapidwright_data2.zip (2024.1.0)

It looks like a stale "parts.db" file got included in the Thanks for reporting this issue! |

To be honest, I don't know anything about java, I learn this tool with the goal of improving PnR about vivado (gain insight into the architecture of FPGA and try to update verilog code structure or constraints), I'm not sure if this tool is still right for me. |

You can also use RapidWright in Python if that is easier for your development environment (see https://www.rapidwright.io/docs/Install_RapidWright_as_a_Python_PIP_Package.html). Feel free to share specifics about what you are trying to do and we can try to support you the best we can. |

It looks like RapidWright is having a problem trying to extract the clock timing constraint from the XDC constraints in the DCP. The design has set of XDC constraints that are stored in different One way to work around the issue is to modify the XDC constraint before calling RWRoute. For example, public static void main(String[] args) {
Design d = Design.readCheckpoint("<DCP_NAME_HERE>.dcp");
for (ConstraintGroup cg : ConstraintGroup.values()) {
List<String> lines = d.getXDCConstraints(cg);
for (int i=0; i < lines.size(); i++) {
if (lines.get(i).contains("-period")) {
lines.set(i, lines.get(i).replace("$peri", "<CLK_PERIOD_HERE>"));
}
}
}
RWRoute.routeDesignFullTimingDriven(d);
} |

The code I modified earlier didn't compile, so I got the same result. 297 ConstraintGroup[] constraintGroups = {ConstraintGroup.NORMAL, ConstraintGroup.LATE};
298 //TODO CHECK which constraint to use. The maximum one as default?
299 for (ConstraintGroup group : constraintGroups) {
300 List<String> constraints = design.getXDCConstraints(group():
301 for (String constraint : constraints) {
302 System.out.println(constraint);
303 if (constraint.contains("-period")) {
304 int startIndex = constraint.indexOf("-period");
305 System.out.println(constraint.substring(startIndex+0, startIndex+70))
306 treq = Math.max(treq, Float.parseFloat(constraint.substring(startIndex+7, startIndex+13)));
......I add the line 302 and line 304 to find out the error constraint, Two questions:
set_property src_info {type:XDC file:7 line:16export:INPUT save:INPUT read:READ} [current_design]

I have created a fix for this issue in this PR: #1037, please give it a try, it should avoid this problem. To answer your questions, the constraints are stored inside the DCP. We can add/remove and modify them inside RapidWright using the APIs on the |

The command
./gradlew compileJavaneeds network, but in my case, I don't have the network, I had download the gradle in the other computer and move to my work computer; but there still have a lot of files to be downloaded, I don't know which file should be changed.And a important issue "Does this software work without the internet connection after environment configuration has been done?"
