通用记录(通过 vhdl 2008 通用包尝试)

So I tried (note: Iam not working with records here, I am just trying to get access to a generic package from a generic component, where I parameterize(?) the package with the parameters of the component):entity genericPackagePart is generic( outputValue : integer ); port( result: out integer );end entity;architecture behav of genericPackagePart is package test is new work.genericPackage generic map( genSize => outputValue ); use work.test.all;begin result <= dummy; -- dummy is a constant from genericPackage set to the value genSize (generic parameter)end architecture;但是我从modelsim得到以下错误:However I get the following errors from modelsim:** Error: (vcom-11) Could not find work.test.** Error: genericPackagePart.vhd(17): (vcom-1195) Cannot find expanded name "work.test".** Error: genericPackagePart.vhd(17): Unknown expanded name.** Error: genericPackagePart.vhd(19): (vcom-1136) Unknown identifier "dummy".** Error: genericPackagePart.vhd(20): VHDL Compiler exiting更新:我尝试将 genericPackagePart 包装在一个通用包中，并使用泛型从该包中实例化 genericPackage ，这也不起作用.Update:I tried wrapping the genericPackagePart in a generic package and to instantiate the genericPackage from within that package with the generics, this did not work either.流程应该是:Testbench => 使用通用参数实例化 genericPackagePart 和 genericPackage该记录在 genericPackage 的测试平台中可用Inside genericPackagePart genericPackage 使用传递给 genericPackagePart 的参数实例化记录在 genericPackagePart 中可用Testbench => Instantiate genericPackagePart and genericPackage with generic parametersThe record is available in the testbench from genericPackageInside genericPackagePart genericPackage is instantiated with the parameters passed to genericPackagePartthe record is available inside genericPackagePartModelsim 给出了错误(test 是我给genericPackagePart 中genericPackage 的参数化实例起的名字，这是来自genericPackagePart 的编译代码>genericPackagePart):Modelsim gave Errors (test is the name I gave to the parameterizes instance of genericPackage in genericPackagePart, this is from the compile of genericPackagePart):** Error: (vcom-11) Could not find work.test.** Error: genericPackagePart.vhd(11): (vcom-1195) Cannot find expanded name "work.test".** Error: genericPackagePart.vhd(11): Unknown expanded name.** Error: genericPackagePart.vhd(13): near "entity": expecting END我查看了将泛型传递给记录端口类型，但这并没有解决基于泛型的包实例化问题I looked at Passing Generics to Record Port Types but that does not solve the issue of the package instantiation based on generics为了完整起见，这里是包和测试平台:For completness here is the package and a testbench:包装:package genericPackage is generic(genSize : integer := 1); constant dummy : integer := genSize;end package;测试平台:package myGenericPackage is new work.genericPackagegeneric map( genSize => 5);use work.myGenericPackage.all;entity genericPackageTestbench isend entity;architecture testbench of genericPackageTestbench is signal testsignal : integer; signal testsignal2 : integer; signal dummy : integer := 12; component genericPackagePart is generic( outputValue : integer ); port( result: out integer ); end component;begin test : process is begin wait for 20 ns; testsignal <= dummy; wait for 20 ns; testsignal <= work.myGenericPackage.dummy; wait; end process; testPart: genericPackagePart port map(result => testsignal2) generic map(outputValue => 128);end architecture;推荐答案我认为问题是你的包 test 需要定义在实体区，而不是架构区:I think the problem was that your package test needs to be defined in the entity area, not the architecture area:package genericPackage is generic(genSize : integer := 1); constant dummy : integer := genSize;end package;entity genericPackagePart is generic(outputValue : integer); port(result : out integer); -- *** Generic package instantiated here *** package test is new work.genericPackage generic map(genSize => outputValue);end entity;architecture behav of genericPackagePart is use test.all;begin result <= dummy; -- dummy is from genericPackage (=genSize)end architecture;这是我测试它的方式(基于您的测试平台):Here's how I tested it (based on your testbench):package myGenericPackage is new work.genericPackage generic map(genSize => 5);use work.myGenericPackage.all;entity genericPackageTestbench isend entity;architecture testbench of genericPackageTestbench is signal testsignal : integer; signal testsignal2 : integer;begin test : process is begin testsignal <= work.myGenericPackage.dummy; wait for 20 ns; assert testsignal = work.myGenericPackage.dummy report "test signal should be work.myGenericPackage.dummy" severity error; assert testsignal2 = 128 report "testsignal2 /= 128" severity error; report "testsignal = " & integer'image(testsignal); report "testsignal2 = " & integer'image(testsignal2); report "Finished"; wait; end process; testPart : entity work.genericPackagePart generic map(outputValue => 128) port map(result => testsignal2);end architecture;使用 Modelsim 10.2 编译和仿真:Compiled and simulated with Modelsim 10.2:vcom -2008 genpacktest.vhd; vsim -c genericPackageTestbench -do "run -all; quit"哪些报告:# Loading std.standard# Loading work.genericpackage# Loading work.mygenericpackage# Loading work.genericpackagetestbench(testbench)# Loading work.genericpackagepart(behav)# run -all# ** Note: Finished# Time: 20 ns Iteration: 0 Instance: /genericpackagetestbench# ** Note: testsignal = 5# Time: 20 ns Iteration: 0 Instance: /genericpackagetestbench# ** Note: testsignal2 = 128# Time: 20 ns Iteration: 0 Instance: /genericpackagetestbench# quit 这篇关于通用记录(通过 vhdl 2008 通用包尝试)的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
