testNetGenerator

public static String testNetGenerator(String dcp,
                                      String edif,
                                      Collection<String> nets,
                                      Collection<String> siteInsts)

Generates RapidWright test code from a provided checkpoint that instantiates the provided nets and siteInsts, and adds the associated PIPs to each of the nets.

Parameters:

dcp - The path to the desired DCP to generate code from.

edif - The path to the external EDIF file to load (in case of an encrypted DCP file).

nets - A collection of nets to generate code for.

siteInsts - A collection of site instances to generate code for.

Returns:

The resulting code.

public static String testNetGenerator(Design design,
                                      Collection<String> nets,
                                      Collection<String> siteInsts)

Generates RapidWright test code from a provided checkpoint that instantiates the provided nets and siteInsts, and adds the associated PIPs to each of the nets.

Parameters:

design - The design to generate code from.

nets - A collection of nets to generate code for.

siteInsts - A collection of site instances to generate code for.

Returns:

The resulting code.

createTestNet

public static Net createTestNet(Design design,
                                String netName,
                                String[] pips)

addPIPs

public static void addPIPs(Net net,
                           String[] pips)

routeSiteNet

public static void routeSiteNet(SiteInst si,
                                Net n,
                                String... siteWires)

Shorthand method to route site wires with a particular net in a site instance.

Parameters:

si - The site instance to target

n - The net to be site routed

siteWires - The list of site wire names to route

addSitePIPs

public static void addSitePIPs(SiteInst si,
                               String... sitePIPs)

Shorthand method for turning on site PIPs in a site instance.

Parameters:

si - The target site instance.

sitePIPs - The list of site PIPs (of the format :) to turn on.

genCell

public static Cell genCell(SiteInst si,
                           String name,
                           boolean isRoutethru,

                           String bel,
                           String... pinMaps)

Shorthand method for creating a placed cell inside a site instance. This is mostly useful for constructing test case scenarios.

Parameters:

si - The target site instance

name - Name of the cell to create

isRoutethru - Flag indicating if the cell should be a routethru

type - The type of the cell (Unisim or special field)

bel - The name of the BEL where the cell should be placed

pinMaps - A variable number of pin mappings for the cell where each string is of the format :

Returns:

The created cell.

genCodeForTestSite

public static void genCodeForTestSite(SiteInst inst,
                                      PrintStream ps,
                                      boolean includeRouting)

Creates boilerplate code for a test by re-creating a SiteInst's configuration from scratch in RapidWright APIs. This is useful for testing when only a small context is necessary to reproduce a specific scenario.

Parameters:

inst - The instance to replicate in the test

ps - The PrintStream (System.out, or a file-based PrintStream, for example).

simplifyNames - Flag indicating that the cell and and net names should be simplified.
